Bradycardia may be common for many physically active adults, who have a resting heart rate below 60 BPM with no negative effects. Take the Sudden Cardiac Arrest Quiz. The electrical problem slows down the time in between heartbeats. [15] Transvenous pacing may be required if the cause of the bradycardia is not rapidly reversible. Bradycardia treatment depends on the underlying cause of the low resting heart rate but may also include the surgical placement of a pacemaker. First and foremost, this is an anomaly of the development of the cardiovascular system. In the case of first-degree heart block, all electrical signals from the sinoatrial node make their way to the atrioventricular node, though impulses may be occurring at a slower rate. Evaluation involves determining the association of symptoms with heart rate and an assessment of underlying cardiovascular conditions. In particular, they include acute effects on the body of low temperature, prolonged fasting, accompanied by metabolic disorders, vagotonia and various infectious processes (typhus, hepatitis, meningitis).
