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.
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 ]
Cardiotonic agents, also known as cardiac inotropes or stimulants, have a positive impact on the myocardium (muscular layer of the heart) by enhancing its contractility. . Unlike general inotropes, these agents exhibit a higher level of specificity as they selectively target the myocar
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 ...
These devices are quite good at finding heart problems such as arrhythmias. [1] They are now used to help diagnose, monitor, and treat various heart conditions. [14] Formal research has found that current smartwatch apps can detect abnormal heart rhythms, like atrial fibrillation and alert people to this.
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 ...
Nick Dunlap, a 20-year-old sophomore who plays golf for the University of Alabama, won the American Express tournament Sunday at the PGA West golf course in La Quinta, California.
[14] [15] [16] Bisoprolol, carvedilol, and sustained-release metoprolol are specifically indicated as adjuncts to standard ACE inhibitor and diuretic therapy in congestive heart failure, although at doses typically much lower than those indicated for other conditions. Beta blockers are only indicated in cases of compensated, stable congestive ...
