Back to Cardiac Medications Front Page Back to Antidysrhythmic Medications Classifications What is an Antidysrhythmic drug?Antiarrhythmics are medications that prevent and treat a heart rhythm that is too fast or irregular also known as arrhythmias. Arrhythmia involves a problem with your heart's electrical system. Your heart may beat too quickly, too slowly or erratically (irregularly).
What are the two classes of Antidysrhythmic?Only two calcium channel blockers—verapamil and diltiazem—are employed as antidysrhythmics. As indicated in Fig. 41.2, calcium channel blockade has the same effect on cardiac action potentials as does beta blockade.
Which cardiac rhythms are treated using Antidysrhythmic medications?Antidysrhythmics, also known as antiarrhythmics, are drugs used to prevent abnormal cardiac rhythms such as atrial fibrillation, atrial flutter, ventricular tachycardia, and ventricular fibrillation. These drugs work by blocking sodium, potassium, and calcium channels in the heart muscles.
Which of the following is a goal of Antidysrhythmic medications?Antidysrhythmic medications are widely used to treat or prevent abnormalities in cardiac rhythms.
