Nurse Teaching on Antiarrhythmic Medication Classes

Patient was educated that antiarrhythmic medications are basically grouped into four classes. Medications belonging to these four classes act differently to exert their antiarrhythmic effect. The four classes are as follows: Class I antiarrhythmic medications These medications block the sodium channels in the cardiac muscle to exert their antiarrhythmic effect and so, are called sodium channel blockers. These medications inhibit arrhythmias by inhibiting the depolarization of cardiac tissues and slowing down the conduction velocity of [...]

Nurse Teaching on Antiarrhythmic Medications and General Mechanism of Action

Patient was educated that antiarrhythmic medications act by numerous mechanisms to prevent the initiation and conduction of abnormal cardiac impulses, thus inhibiting arrhythmias. The usual mechanisms of action of antiarrhythmic medications are as follows: Inhibiting the depolarization Inhibition of depolarization of cardiac muscle helps with preventing initiation of an impulse that is out of the normal cardiac rhythm, thus inhibiting arrhythmia. Slowing down of conduction velocity Slowing down the conduction of an impulse along the [...]

Precautions to be Exercised While Using Alpha-1 Adrenoceptor Antagonists-2

Patient was educated regarding precautions to be exercised while using Alpha-1 adrenoceptor antagonists as follows: Try changing the positions very slowly, as sudden change of positions can make the hypotensive episodes even worse and precipitate accidents and falls. Alpha-1 adrenoceptor antagonists are contraindicated in individuals with abnormally high heart rates. So, if your heart rate is being abnormally high (consistently more than 100), with the use of these medications, report this to your physician immediately. [...]

Precautions to be Exercised While Using Alpha-1 Adrenoceptor Antagonists-1

Patient was educated regarding precautions to be exercised while using Alpha-1 adrenoceptor antagonists as follows: Be aware of signs and symptoms of hypotension, to avoid any episodes of altered levels of consciousness and accidental falls. One should stay away from activities, such as, driving and operating heavy machinery, until they are used to the side effects caused by Alpha-1 adrenoceptor antagonists. Alpha-1 adrenoceptor antagonists are contraindicated in individuals with abnormally low blood pressures. Use of [...]

Contraindications for Alpha-1 Adrenoceptor Antagonist Use

Patient was educated on contraindications for Alpha-1 adrenoceptor antagonist use as follows: Alpha-1 adrenoceptor antagonists are contraindicated in individuals with abnormally high heart rates. So, if your heart rate is being abnormally high (consistently more than 100), with the use of these medications, report this to your physician immediately. Alpha-1 adrenoceptor antagonists are contraindicated in individuals with abnormally low blood pressures. Use of these medications in these individuals can result in extremely low blood pressure [...]
