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 ).

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 ECG there reportedly showed an irregular tachycardia, and the patient was immediately referred to the emergency room. Here is her ECG on arrival: There is a wide complex tachycardia that is irregularly irregular (this is difficult to determine at these very high rates). Vitals were within normal limits other than heart rate.

2 weeks Here is the final electrophysiology note: It is unclear what precipitated his motor vehicle collision. Sinus Tachycardia ( common in any trauma patient. ). Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ).

Volta Medical has announced it has entered into a Joint Development Agreement with GE Healthcare to enhance arrhythmia procedures with artificial intelligence (AI)-driven electrophysiology technologies. 1 Approximately 33 million patients worldwide are living with AFib.

Initial vital signs include: NIBP 99/58 HR 150-160 (trend) RR 10 (spontaneous, but shallow) SpO2 86 (RA) BBS CTA The initial rhythm strip is attached: Figure 1 There is a wide complex tachycardia of varying morphology, amplitude, and R-R cycle length. The rS configuration in Lead I displays a persistent rightward axis.
