Second degree type 2 atrioventricular block symptoms?
summary
Second degree atrioventricular block is a partial conduction block in the process of electrical stimulation from atrium to ventricle, that is, ventricular leakage phenomenon, which may be accompanied by atrioventricular conduction delay. Second degree atrioventricular block can be divided into two types, second degree type 1 and second degree type 1. Second degree type 1 is also known as Wendt type. Most people with normal atrioventricular conduction function can induce Wendt type atrioventricular block when rapid atrial pacing. In addition, progressive atrial pacing can also lead to one degree, 2:1 or high degree of atrioventricular nodal block. Second degree type 2 atrioventricular block symptoms? Let's talk about it
Second degree type 2 atrioventricular block symptoms?
It depends on the degree of conduction block and the speed of ventricular rate. When the degree of block is light, there is little ventricular leakage, little effect on hemodynamics, no obvious symptoms, or only palpitation. If the heart rate slows down to below 50 beats / min due to more ventricular leakage, dizziness, weakness, decreased blood pressure and other symptoms of decreased cardiac output may appear.

Severe type II atrioventricular block can significantly slow down the ventricular rate, accompanied by obvious symptoms such as syncope, loss of consciousness, and attack of A-S syndrome, pacemakers need to be implanted to avoid long-term cardiac arrest, leading to life-threatening.
matters needing attention
It is helpful to prevent the second degree type-1 conduction block that diet is regular, daily life is regular, mood is comfortable, work and rest is moderate, avoid external evil, take part in physical exercise properly to strengthen the physique, avoid using some antiarrhythmic drugs.
