“Normal” Sinus Rhythm Rhythm: Regular Rate: “Normal” (60-100-ish) P Waves: “Normal” and upright, one for each QRS PR Interval: “Normal” (0.12-0.2 seconds) QRS Complex: “Normal” (0.08-0.12 seconds) Sample: Sinus Bradycardia Rhythm: Regular Rate: Slow (<60 bpm) P Waves: “...
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....

How long should the PR interval be for normal sinus rhythm? .2 seconds (1 big box or 5 small boxes) How long should the QT interval be in normal sinus rhythm? .4 seconds (2 big boxes or around 13 small boxes). What is the QT interval? Beginning of QRS complex to end of T wave...
A high frequency potential with short duration, preceding the QRS has been described as the Purkinje potential (Figure 2). This has also been called P potential and diastolic potential. P potentials can be recorded both in sinus rhythm and during ventricular tachycardia. Pacing at sites manifesting...

In athletes, resting sinus bradycardia is a common finding due to increased vagal tone; it is particularly prevalent in endurance athletes. A junctional escape (or nodal) rhythm occurs when the QRS rate is faster than the resting P-wave or sinus rate, which is typically slower in athletes ...
