Explanation:
Beta-blockers, also known as anti-anginal vasodilators, such as acebutolol, atenolol, betaxolol, bisoprolol,
carteolol, carvedilol, esmolol, metoprolol, nadolol, pindolol, propranolol, sotalol, and timolol; nitrates
Explanation:
The EKG's horizontal component measures duration. The duration of the smaller squares is.04 seconds, while
the duration of the larger squares is.20 seconds.
Explanation:
Pacemakers are categorized using a 5-position code that outlines the various pacemaker kinds and their
purposes. The chamber or chambers being paced are indicated by position one (I). Position two (II) denotes
the detected chamber or chambers. The device's reaction to sensing is indicated in position three (III). The
programmability and rate of modulation function are shown in position 4 (IV). The only uses for position five
(V) are tachycardia-related.
Explanation:
Alpha-adrenergic antagonists lower blood pressure, enhance vasodilation, and reduce vascular tone.
Alpha-adrenergic antagonists are used therapeutically to treat hypertension, pheochromocytoma, and the
extravasation of tissue-toxic substances.
Explanation:
Using Doppler flow studies can help distinguish intermittent claudication.
Explanation:
Depending on the severity and extent of the ailment as well as the presence of other concomitant
cardiovascular conditions, second-degree atrioventricular block type II is treated differently. Maintaining
cardiac output while restoring sinus rhythm is the aim of treatment.
Explanation:
On an EKG, the electrolyte abnormality hypercalcemia will show shortened QT intervals and ventricular
repolarization.
