Pharmacologic management of ACM involves arrhythmia suppression and prevention of thrombus formation. Sotalol, a beta blocker and a class III antiarrhythmic agent, is the most effective antiarrhythmic agent in ACM. Other antiarrhythmic agents used include amiodarone and conventional beta blockers (i.e.: metoprolol). If antiarrhythmic agents are ...
Amiodarone should only be used to treat adults with life-threatening ventricular arrhythmias when other treatments are ineffective or have not been tolerated. [ 5 ] Dofetilide blocks only the rapid K channels; this means that at higher heart rates, when there is increased involvement of the slow K channels, dofetilide has less of an action ...
Metoprolol, sold under the brand name Lopressor among others, is a medication used to treat angina, high blood pressure and a number of conditions involving an abnormally fast heart rate. [4] It is also used to prevent further heart problems after myocardial infarction and to prevent headaches in those with migraines . [ 4 ]
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia.
Agents specifically labeled for cardiac arrhythmia Esmolol, [94] sotalol, [95] landiolol (Japan) [96] Agents specifically labeled for congestive heart failure [80] Bisoprolol, carvedilol, sustained-release metoprolol; Agents specifically labeled for glaucoma Betaxolol, [93] carteolol, [93] levobunolol, [93] timolol, [93] metipranolol [97]
Arrhythmias, also known as cardiac arrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. [2] Essentially, this is anything but normal sinus rhythm . A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia , and a resting heart rate that is too slow – below ...
Proarrhythmia is a new or more frequent occurrence of pre-existing arrhythmias, paradoxically precipitated by antiarrhythmic therapy, which means it is a side effect associated with the administration of some existing antiarrhythmic drugs, as well as drugs for other indications. In other words, it is a tendency of antiarrhythmic drugs to ...
Nadolol is used to treat hypertension and for long-term treatment of angina pectoris and is approved by the FDA for these purposes. [8]It is regularly used off-label [8] for control of heart rate in people with atrial fibrillation, [9] prevention of migraine headaches; [10] prevention of bleeding veins in people with portal hypertension caused by cirrhosis; [4] and to treat people with high ...
