Lindsay, MD (1923-1987) master teacher of electrocardiography, friend, mentor, and colleague. Many of the excellent ECG tracings illustrated in this learning program are from Dr. The materials presented in the “Introduction to ECG Interpretation” Booklet are for your information only. You accept all risk of use of, and reliance on, the materials contained in the Booklet. This document and the ECG website offer an introduction to clinical electrocardiography. ECG terminology and diagnostic criteria often vary from book to book and from one teacher to another. In this document an attempt has been made to conform to standardized terminology and criteria, although new diagnostic concepts derived from the recent ECG literature have been included in some of the sections. The sections in this booklet are organized in the same order as the recommended step- wise approach to ECG interpretation outlined in Section 2 (p7). Beginning students should first go through the sections in the order in which they are presented. Others may choose to explore topics of interest in any order they wish. It is hoped that all students will be left with some of the love of electrocardiography shared by Dr. This list (updated in 2016) is provided on the following page and is also found on http://ecg. Students of electrocardiography are encouraged to study this list and become familiar with the ECG recognition of these diagnoses. Most of the diagnoses are illustrated in this document. This section describes the basic components of the ECG and the standard lead system used to record the ECG tracings. The diagram illustrates ECG waves and intervals as well as standard time and voltage measures on the ECG recordings. 0 It is important to recognize that lead I (and to a lesser extent aVL) are right -to- left in direction. Also, lead aVF (and to a lesser extent leads II and III) are superior -to- inferior in direction. The diagrams on the next page further illustrate the frontal plane and chest lead hookup. Precordial lead placement V1: 4th intercostal space (IS) adjacent to right sternal border V2: 4th IS adjacent to left sternal border V3: Halfway between V2 and V4 V4: 5th IS, midclavicular line V5: horizontal to V4; anterior axillary line V6: horizontal to V4-5; midaxillary line (Note: in women with large breasts, V4-6 leads should be placed under the breast surface as close to the 5th IS as possible) 6 2. Like the approach to a physical exam, it is important to follow a standardized sequence of steps in order to avoid missing subtle abnormalities in the ECG tracing, some of which may have clinical importance. The 6 major sections in the "method" should be considered in the following order: 1. MEASUREMENTS (usually made in the frontal plane leads): Heart rate (state both atrial and ventricular rates, if different) PR interval (from beginning of P to beginning of QRS complex) QRS duration (width of most representative QRS) QT interval (from beginning of QRS to end of T) QRS axis in frontal plane (see "How to Measure QRS Axis" on p 8) 2. CONDUCTION ANALYSIS: "Normal" conduction implies normal sino-atrial (SA), atrio-ventricular (AV), and intraventricular (IV) conduction. WAVEFORM DESCRIPTION: Carefully analyze each of the12-leads for abnormalities of the waveforms in the order in which they appear: P-waves, QRS complexes, ST segments, T waves, and…. FINAL ECG INTERPRETATION: This is the conclusion of the above analyses. Occasionally the term "borderline" is used if unsure about the significance of certain findings or for minor changes. Examples of "abnormal" statements are: Inferior MI, probably acute Old anteroseptal MI 7 Left anterior fascicular block (LAFB) Left ventricular hypertrophy (LVH) Right atrial enlargement (RAE) Nonspecific ST-T wave abnormalities Specific rhythm abnormalities such as atrial fibrillation Example of a 12-lead ECG interpretation using the “Method”: Mearurements: Rhythm (s): Conduction: Waveform: Interpretation: A= 67 V=67 Normal sinus Normal SA, rS in II, III, aVF; Abnormal ECG: PR=180 ms rhythm AV, and IV SIII > SII ; Left Anterior Fascicular Block QRS=90 ms conduction Small q in I, aVL; QT=400 ms Poor R progression Axis= -50 V1-4 6. These changes may have important implications for clinical management decisions. How to Measure the Frontal Plane QRS AXIS: INTRODUCTION: The frontal plane QRS axis represents the average direction of all ventricular depolarization forces in the frontal plane leads. As such this measure can inform the ECG reader of changes in the sequence of ventricular activation (e. In the next diagram the normal range is shaded grey (-30° to +90°). In the adult left axis deviation (see: superior, leftward blue arrow) is defined from -30° to -90°, and right axis deviation (see: inferior, rightward blue arrow) is defined from +90° to +180°. From -90° to ±180° is very unusual and is often due to lead placement error. This is often the lead with the smallest QRS complex. Isoelectric More likely axis Less likely axis Lead I +90 -90 II -30 +150 III +30 -150 aVR -60 +120 aVL +60 -120 aVF 0 +/-180 If there is no isoelectric lead, there are usually two leads that are nearly isoelectric, and these are always 30° apart on the diagram. Find the perpendiculars for each lead and chose an approximate QRS axis within the 30° range. An axis cannot be determined and is called indeterminate. Lead aVF is the isoelectric lead (note: equal forces positive and negative). Therefore, of the two choices, the axis has to be 0°. Lead aVR is closest to being isoelectric (but slightly more positive than negative) 2. Note that Lead I is mostly negative; lead III is mostly positive. Because aVR is slightly more positive, the axis is slightly beyond +120° (i. The following "normal" ECG characteristics, therefore, are not absolute. It takes considerable ECG reading experience to discover all the 11 normal variants. The normal 12-lead ECG illustrated below is an example of the usual 4- channel continuous 10 second recording including the V1 rhythm strip. Mearurements: Rhythm (s): Conduction: Waveform: Interpretation: A=55 V=55 Normal Sinus Normal SA, Normal P, QRS, ST, Normal ECG PR=140 Rhythm AV, and IV and U QRS=106 conduction QT=440 uncorrected Axis= +80 I. For example, normal QT is: QT 380 ms @ 80 bpm QT 420 ms @ 60 bpm Frontal Plane QRS Axis: +90° to -30° (in the adult) II. Normal CONDUCTION: Normal Sino-Atrial (SA), Atrio-Ventricular (AV), and Intraventricular (IV) conduction IV. Normal WAVEFORM DESCRIPTION: 12 P Wave: It is important to remember that the P wave represents the sequential activation of the right and left atria, and it is common to see notched (lead II) or biphasic P waves (Lead V1) of right and left atrial activation. Two determinates of QRS voltages are: Size of the ventricular chambers (i. This gives rise to asymmetrical T waves in most leads (see below). The ST segment occurs during Phase 2 (the plateau) of the myocardial cell action potentials. In some normal individuals, particularly women, T waves can be more symmetrical with a distinct horizontal ST segment.

Early reports correlating a positive crossm atch between recipient serum and donor lym phocytes with hyperacute rejection of transplanted kidneys led to establishing tests of recipient sera as the standard of practice in transplantation. H owever, Lymphocytotoxicity: controversy rem ains regarding 1) the level of sensitivity needed for crossm atch testing; Auto–crossmatch vs allo–crossmatch 2) the relevance of B-cell crossm atches, a surrogate for class II incom patibilities; 3) the T or B cell relevance of immunoglobulin class and subclass of donor-reactive antibodies; 4) the significance of historical antibodies, ie, antibodies present previously but not at the time of transplantation; Short/long/wash/AHG methods 5) the techniques and type of analyses to be perform ed for serum screening; and 6) the IgG vs IgM appropriate frequency and timing of serum screening. Despite a number of variables, when Flow cytometry the data from reported studies are considered collectively, several observations can be Enzyme-linked immunosorbent assay m ade. H um an leukocyte antigen–donor-specific antibodies present in the recipient at the tim e of transplantation are a serious risk factor that significantly dim inishes graft function and graft survival. Antibodies specific for human leukocyte antigen class II antigens (HLA-DR and -DQ) are as detrimental as are those specific for class I antigens (HLA-A, -B, and -C). The degree of risk resulting from H LA-specific antibodies varies am ong im m unoglobulin classes, with im m unoglobulin G antibodies representing the m ost serious risk.

Because completely mismatched kidney transplantations function well over long periods, an alternative approach might begin with the hypothesis that six-antigen “mismatched” transplantations were not Associated human leukocyte Approximate completely mismatched. Interest in reevaluating the potential roles CREG* antigen gene products “epitope” frequency, % of cross-reactive groups (CREGs) in transplantation is one such 1C A1,3,9,10,11,28,29,30,31,32,33 80 approach. In the early days of serologic HLA testing, a high panel 2C A2,9,28, B17 66 reactive antibody sera was considered to be composed of many anti- 5C B5,15,17,18,35,53,70,49 59 HLA antibodies. It was later noted, however, that sera of highly sensi- 7C B7,13,22,2740,41,47,48 64 tized patients awaiting solid organ transplantation were generally com- 8C B8,14,16,18 37 posed of a small number of antibodies directed at public antigens, also 12C B12,13,21,40,41 44 called CREGs, rather than multiple antibodies, each reacting with a 4C A24,25,32,34, Bw4 85 specific conventional HLA antigen. Furthermore, the frequency of the 6C Bw6, Cw1,3,7 87 CREGs was much higher, eg, 35% to 88% , than that of even the most common HLA-A and -B antigens. By inference, therefore, matching for donor and recipient antigens included in the same CREG, ie, CREG C refers to major public epitope or cross-reactive groups (CREG). In addition, because of the inclusion of several private HLA-A and -B antigens within a single CREG, a number of relatively rare antigens can be matched more easily, offering the possibility of improved graft survival for a greater number of both white and nonwhite patients. Recent large registry analyses for that patient, and if accepted by the transplantation center, was of the role for H LA m atching in renal transplantation consistently shipped for transplantation. Based on these results the United except in the case of patients with six antigen m atches.

Each cadaveric donor type was compared by a pairs in which the donor could have fewer antigens than the recipient, computer search with the HLA types of all patients awaiting kidney provided none were m ism atched.

M ost of the published Serology versus M olecular (antibody defined) (Low Intermediate High resolution) transplantation outcom e data is based on serologic testing and assignm ent of antigens.

The question has now becom e one of what level of H LA testing is useful clinically for m atching purposes in renal transplantation. Although this issue has not been resolved, recent HLA-DR6 data published from the European Registry upholds the positive effect that “correct” HLA matching has had on renal graft outcome.
