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 ...

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 ...

Although a normal QT interval imparts a much lower risk of life ... Owing to multiple variables interacting at any given time, patients may have different QT intervals during subsequent ECG ...

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, ...

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

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 ...

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 ...
