Abstract:
The study of J waves and slurs and their association with cardiovascular death is clouded by the lack of a standardized coding or classification methodology. Over the past three years of studying these ECG patterns, we have evolved a Data Entry Form that is designed to resolve some of the key issues. These issues include the effect of other ECG findings, whether the QRS-ST junction occurs before or after the J waves, if contiguous leads are required and rules to distinguish J waves from fragmented QRS complexes. This form is now being used to code the ECGs of 44,000 VA patients and the follow up is being extended to 15years to resolve these issues.

An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage. When...
01:25Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
