Which term refers to enlargement of the heart muscle that may accompany an increased ventricular cavity?

Explanation:
Enlargement of the heart muscle due to repeated or sustained increased workload is cardiac hypertrophy. The myocardium thickens and can be associated with a larger ventricle cavity in what’s known as eccentric remodeling, a response to volume overload. This term specifically describes growth of the heart muscle itself, unlike bradycardia (slow heart rate), atherosclerosis (arterial plaque), or ejection fraction (a measure of how much blood is pumped per beat). So the correct term is cardiac hypertrophy.
