The Normal ECG. A normal ECG contains waves, intervals, segments and one complex, as defined below. ... The waves on an ECG include the P wave, Q wave, R wave, S wave, T wave and U wave.

All you really need to know to spot a problem on the ECG is your four-times table and the normal waveform interval values. Assuming standard paper speed of 25mm/sec, then one small square = 0.04msec.

This document will assist physicians in identifying normal ECG patterns commonly found in athletes. ... QRS after every P wave and (3) normal P wave axis (frontal plane 0–90°s). This figure is only ...

It is important to check whether the patient is in sinus rhythm — that is, the rhythm is originating in the sinoatrial node, which is represented by the presence of normal P-waves. When reviewing an ...

Common normal athletic ECG patterns he chose to highlight included the inverted P-wave and junctional rhythm, Mobitz type I Wenckebach block, and sinus arrhythmia.

The QRS complexes are narrow (0.08 sec) and have a normal morphology and normal axis between 0° and +90° (positive QRS complex in leads I and aVF). The average heart rate is 42 bpm. The QT/QTc ...

Learning the art of ECG interpretation requires intellect, commitment, effort and — perhaps most importantly — an organized approach. I have spent thousands of hours (yes, thousands) looking ...

In a normal reading, both the ST segment and the T wave shows no signs of flattening, sharp spikes, or depressions. By contrast, an ECG reading of a severely diseased heart is noticeably different.
