WebNov 8, 2024 · The EKG rhythm will appear irregular when SA block occurs with a normal or slow heart rate. The P wave will be normal and the PR interval will be normal (0.12-0.20 sec). The QRS complex will typically be normal (0.06-0.10 sec). The pause time is an integer multiple of the p-p interval. In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration. The PR interval is sometimes termed the PQ interval. bunny rabbit clip art black and whiteWebAn average RR interval of as long as 2000ms at rest (which is equivalent to a resting heart rate of 30beats/min) and a PR interval of 400ms have been reported in healthy highly … bunny rabbit clip art
