The normal range of the ECG differed between men and women: heart rate 49 to 100 bpm vs. 55 to 108 bpm, P wave duration 81 to 130 ms vs. 84 to 130 ms, PR interval 119 to 210 ms vs. 120 to 202 ms, QRS duration 74 to 110 ms vs. 70 to 104 ms, QT inter...
The P-wave amplitude may be increased and the PR interval is often slightly prolonged. The changes in the ECG correlate with the plasma K level fairly well,being found in 78% of patients with plasma K below 2.7 meq/liter, in 35 % of those with K between 2.7 and 3.0 meq/liter, and ...
the normal heart axis is between –30° and 90°. If the axis is more positive than 90° it is referred to as right axis deviation. If the axis is more negative than –30° it is referred to as left axis deviation. The axis is calculated (to the nearest degree) by the ECG machine...
An apparently normal ECG is defined by the following [30]: 1) heart rate between 55 and 100 bpm; 2) presence of P waves in all leads, with normal morphology; 3) presence of a QRS complex following each P wave; 4) PR interval between 0.12 to 0.20 seconds; 5) QRS duration ≤ 0.12...

In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect?ECG:An ECG, or electrocardiogram, is an electrical readout of the heart which measures the electrical output of all heart chambers during cardiac cycles. Th...
