Abstract
Chronic apical right ventricular pacing may impair left ventricular function and cause heart failure in patients with indication for antibradycardia pacing and normal left ventricular ejection fraction at baseline, through multiple electro-mechanical changes. We describe the case of a patient who needed an upgrade to cardiac resynchronization therapy and developed angina early after single chamber right ventricular pacing and discuss pacing induced cardiomyopathy.
