Pacemaker sensitivity explained

WebOverview. Depending on your heart condition, your doctor will prescribe either a single or dual chamber pacemaker. This refers to the number of heart chambers that need to be paced or sensed. For single chamber pacing, either the right atrium (upper chamber) or the right ventricle (lower chamber) is paced. Only one pacing lead is used. WebRVAC is designed to dynamically adjust the right ventricular pacing output. ventricular voltage output is automatically adjusted to 0.5 V above the measured threshold. beat-to …
