She was prescribed oral diltiazem to prevent recurrence and was discharged. == MY Comment, by K EN G RAUER, MD ( 10/25 /2022 ): == Today’s blog post reviews the important topic of how to approach the patient who presents with palpitations from an SVT ( S upra V entricular T achycardia ) rhythm. She had an echocardiogram which was normal.

Now it can NEVER have negative concordance though - because the accessory pathways usually insert at base of the heart rather than apex! == MY Comment by K EN G RAUER, MD ( 5/14/2022 ): == What I liked most about today's case — was the skillful use of bedside Echo in the ED by Dr. Smith to facilitate rhythm diagnosis!

Radiofrequency ablation was performed for a right sided posteroseptal bypass tract. What I found especially interesting about this arrhythmia — is the variation in QRS morphology throughout.

By 1909 ECGs were being used to diagnose cases of arrhythmia; by 1910 to diagnose indicators of a heart attack. In April 2022 BMS had received FDA approval for Camzyos, the first drug developed specifically for targeting HCM.

Abstract Introduction The optimized ablation index (AI) value for catheter ablation of atrial fibrillation (AF) remains to be defined. Methods and Results Patients with symptomatic, drug-resistant paroxysmal AF for first ablation were prospectively enrolled from September 2020 to January 2022. vs. 53.3%, p  = .005).

However, he suddenly developed a series of malignant ventricular arrhythmias. Below are printouts of some of the arrhythmias recorded. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. The arrhythmia starts with a PVC having a short coupling interval.

So, we are looking for signs of an underlying regular atrial rhythm ( with perhaps slight sinus arrhythmia ) — and it is much easier to find this when you know what you are looking for!

The possibility of an ischemic cause of the ventricular arrhythmia has to be considered! A workup was undertaken in search of a cause of the patient's ventricular arrhythmia. Once the arrhythmia was under control cardiac MRi was performed. The patient has been scheduled for a PVC ablation procedure. No PVCs are seen.
