Detailed explanation-1: -Causes include increased stimulation threshold at electrode site (exit block), poor lead contact, new bundle branch block or programming problems. ECG findings may be minimal, although presence of pacing spikes within QRS complexes is suggestive of undersensing.
Detailed explanation-2: -If your pacemaker fails, you are at increased risk of stroke and heart failure. The risk of stroke for patients with atrial fibrillation (AFib) increases by five times. The risk of death-related to cardiac problems doubles. Therefore, it is important to seek help as soon as possible.
Detailed explanation-3: -The bundle of myocardial tissue called sino-atrial node present in the right atrium that is responsible for generating the impulse for contraction is called the pacemaker of the heart.
