How to treat second degree atrioventricular block

If the heart rate is not too slow, no special treatment is required. If the patient has obvious symptoms, corresponding treatment should be carried out according to different causes, and various inducing factors should be prevented, such as stopping drugs that inhibit myocardial contractility and reduce heart rate, such as beta blockers. At the same time, the ECG changes should be closely observed to prevent other arrhythmias. If necessary, drug treatment can be considered, such as atropine can increase the heart rate of atrioventricular block, suitable for patients with block occurring in atrioventricular node; isoproterenol is suitable for atrioventricular block at any position; pacemaker treatment should be considered for critically ill patients.
