Tachyarrhythmias , such as nonsustained ventricular tachycardia (NSVT) and atrial fibrillation and flutter (AF), impact right atrial function. In AF, atrial contraction is reduced leading to a decrease in ventricular filling and stroke volume. In NSVT, the systolic volume is diminished due to atri...
, the catheter applies heat or extreme cold to create tiny scars on small areas of your heart. These scars block the path of the faulty electrical signal that’s causing your arrhythmia. Frequently performed to treatsupraventricular tachycardia, it also treats atrial fibrillation and atrial flutter...
With SSS, the heart rate can alternate between slow (bradycardia) and fast (tachycardia), often in combination with atrial fibrillation or atrial flutter. Treatment of SSS may involve a pacemaker and/or medication. View Answer Therapy options Therapy options Learn about related therapy options....
Also, whenever the ventricular rate is about 150 beats/min, always consider the possibility of 2:1 atrial flutter—in this instance, classic flutter waves are often hard to discern, or they may be mistaken for the P waves of AT or sinus tachycardia. If you are unsure of the atrial or ...
Atrial arrhythmias, including atrial fibrillation and flutter, occur in 10% to 30% of patients with heart failure, and the incidence is proportional to the degree of heart failure.32 Therefore it is important for therapists to monitor heart rhythm, on telemetry if available, at baseline, as ...
