This document will assist physicians in identifying normal ECG patterns commonly found in athletes ... until there is a non-conducted P wave with no QRS complex (figure 7). The first PR interval after ...

These lines are comprised of three main parts: In normal sinus rhythm, the P-P interval (the time between consecutive P waves ...

The goal of ECG interpretation in athletes is to classify the ECG as: (1) ‘normal’—no further evaluation needed ... These include findings suggestive of cardiomyopathy such as T-wave inversion, ST ...

In addition to changes in the ECG caused by disease, there are a variety of atypical ECG patterns, often called 'normal variants ... and repolarization (T wave), corresponding to the ST segment ...

This new insight about the interrelation among PERED/weight, amplitude of ECG potentials, and durations of P waves, QRS complexes, and QTc intervals in patients with CHF can be immediately ...

The arrhythmia abruptly terminates, and there is a narrow QRS complex that is preceded by a P wave ... to prolong the QT interval. If the supraventricular complex had a normal QT interval ...

Long QT syndrome is a medical condition that causes abnormal electrical conduction in the heart. When graphed on an electrocardiogram (EKG or ECG) each heartbeat has ...
