Sinus bradycardia can be defined as a sinus rhythm with a resting heart rate of 60 beats per minute or less. However, few patients actually become symptomatic until their heart rate drops to less than 50 beats per minute. The action potential responsible for this rhythm arises from the sinus...

Sinus bradycardia is a regular sinus rhythm but with a SA node rate below 60 bpm (Fig. 41.6). The ECG has normal P waves and P–R intervals and a 1:1 conduction ratio between the atria and ventricles, but an atrial rate of less than 60 bpm. It represents a suppression of the SA ...

Sinus Bradycardia (< 60 BPM) Sinus bradycardia is a rhythm in which the rate of impulses originating in the SA node is lower than normal--a rate of 60 beats per minute or less. Very few patients, however, will actually experience symptoms unless their heart rate drops to < 50 beats per...
sinus bradycardiasinus arrhythmiaThis family of heart rhythms all originate from the sinoatrial node and, assuming that the rate is appropriate, represent the normal heart rhythms of dogs and cats. This group of rhythms includes sinus rhythm, sinus arrhythmia, sinus bradycardia and sinus tachycardia....
