Explanation:

A pacemaker is a surgically - implanted, battery - operated electronic device that regulates the heart's rhythm. A Holter monitor is a portable device for continuous ECG recording. A cardiac stent is for opening blocked coronary arteries. Tissue plasminogen activator is a drug for dissolving blood clots. For the second question, blood clots can be a sign of various heart - related issues including valve defects as abnormal blood flow due to valve problems can lead to clot formation. Diuretics are drugs for increasing urine output and are not indicative of valve defects directly.
