Typically, patients with HCM experience sinus tachycardia and sinus arrest relatively infrequently. Subsequent examinations and follow-up revealed that pacing significantly reduced LVOT obstruction and corrected heart rhythm. To manage the complex comorbidities, we opted for dual-chamber pacemaker implantation.

The electrical conduction system [1] In schematic depiction of a normal sinus rhythm the P-wave represents atrial depolarization, the QRS complex symbolizes ventricular depolarization, and the T-wave indicates ventricular repolarization. Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia.

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.

In an 82-year-old female patient with cardiac dysfunction using digoxin, tachycardia (average heart rate of 93 beats/min) was demonstrated by electrocardiogram (ECG). heart rate was <60 beats/min) and sinus arrest were first detected after 3 months. heart rate was <60 beats/min.

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.

Early treatment of persistent AF can reduce the risk of blood clots, stroke, and heart failure, and may prevent the disease from becoming permanent. Patients are often treated with AADs as frontline therapy for heart rhythm maintenance, though some can experience adverse effects and limited efficacy.

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.
