What arrhythmia is present? Let's first consider the heart rate: with a heart rate of 194 beats/min, the heart rate is too low for atrial flutter (1:1) (except in patients who have been pre-treated with medication), and the rate would be unusually high for atrial flutter with 2:1 conduction.

Unlike paroxysmal AF, which describes symptoms that last for seven days or fewer, persistent AF is a sustained arrhythmia that lasts for more than a week 1. Early treatment of persistent AF can reduce the risk of blood clots, stroke, and heart failure, and may prevent the disease from becoming permanent.

Cardioversion is used to correct abnormal heart rhythms, also known as arrhythmias. When your heart beats too quickly, too slow, or irregularly, it can affect your blood flow and lead to severe complications like stroke or heart failure. Cardioversions can help “reset” your heart rhythm to its regular pattern.

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. Heart Rhythm, 13(7): 1515-1520. [2]:

Notice there is tachycardia. I have warned in the past that one must think of other etiologies of ischemia when there is tachycardia. In this case, the patient had failed to take his atenolol in the AM and was having reflex tachycardia in addition to ACS. But we are now concerned with the precordial leads. BP was 160/100.

Learning points : Takotsubo can lead to cardiac arrest from ventricular arrhythmia. But there are 3 other wide beats in the tachycardia that begins with beat #6 ( = beats #7; 13,14 ). The QTc then gradually shortened over the course of several days as is usual for stress cardiomyopathy.

Antiarrhythmic Drugs WHAT THEY DO : Antiarrhythmic drugs are used to help prevent or treat abnormal heart rhythms, such as atrial fibrillation and ventricular tachycardia. The most common antiarrhythmic drugs for children with congenital heart disease (CHD) include beta-blockers (see above) and sodium channel blockers.
