A normal ECG contains waves, intervals, segments and one complex, as defined below. Wave: A positive or negative deflection from baseline that indicates a specific electrical event. The waves on ...

there are a variety of atypical ECG patterns, often called 'normal variants', that can occur in perfectly normal individuals. SCD is most often due to an extremely rapid and uncoordinated cardiac ...

The goal of ECG interpretation in athletes is to classify the ECG as: (1) ‘normal’—no further evaluation needed or (2) ‘abnormal’—further evaluation needed. Normal ECGs include common, ...

The QT interval is the time from the beginning of the QRS complex, representing ventricular depolarization, to the end of the T wave, resulting from ventricular repolarization. The normal QT ...

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

The QRS complex duration (0.08 sec) and morphology are normal. The QT/QTc intervals are normal (240/350 msec). The axis is rightward between +90° and +180° (negative QRS complex in lead I and ...

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 ...
