The two ECGs above were texted to me with the text: "Young Guy came in in SVT but now in and out of irregular wide complex tachycardia. -- not sure if polymorphic VT vs. a fib with WPW." FINAL Points in Today's CASE: Even though the SPERRI value during AFib in today's case was not below 250 msec. Definitely atrial fibrillation.

The combined solutions are expected to enhance performance and streamline workflows for electrophysiologists during catheter ablation procedures to treat atrial fibrillation , AFib. 1 Approximately 33 million patients worldwide are living with AFib. 1 Approximately 33 million patients worldwide are living with AFib.

She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Answer : The ECG above shows a regular wide complex tachycardia. Said differently, the ECG shows a rather slow ventricular tachycardia with a 2:1 VA conduction. Cardiac output (CO) was being maintained by the tachycardia.

The 2019 ESC Guidelines for the management of patients with supraventricular tachycardia indicated that IV Amiodarone should not be considered in these populations. KEY Point: Nothing other than AFib with WPW results in a ventricular response this fast ( which is why Figure-2 is pathognomonic for AFib in a patient with WPW ).

This strip was obtained: Apparent Wide Complex Tachycardia at a rate of 280 What do you think? Troponins 34>33>43, likely secondary to myocardial injury from tachycardia. The patient was started on amiodarone, anticoagulation, and metoprolol, and scheduled for atrial flutter ablation. He underwent ablation in the EP Lab.

Initial ECG in the ED: Presenting ECG : Wide-complex tachycardia at a rate about 200. This is overwhelmingly likely to be ventricular tachycardia, even if only age and medical history are considered. Nevertheless, the widths of both the QRS complex and the RS duration are similar in both the old ECG and the tachycardia.

Therefore — the rhythm in ECG #1 is almost certain to be AFib ( A trial F ibrillation ) , seen here with a “rapid” ventricular response. Under normal conditions with AFib — the refractory period of the AV node does not allow more than 150-to-200 impulses/minute to be conducted to the ventricles.
