OCTOBER 21, 2023
On the monitor patient had wide-complex tachycardia. Differential is ventricular tachycardia versus supraventricular tachycardia with aberrancy versus sinus tachycardia with a aberrancy. After the patient was stabilized with supportive care, the heart rate gradually slowed, confirming sinus tachycardia.

An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). She was admitted to the ICU where subsequent ECGs were performed: ECG at 12 hours QTc prolongation, resolution of T wave alternans ECG at 24 hours Sinus tachycardia with normalized QTc interval. No ischemic ST changes.

She had acute pulmonary edema on exam. On arrival, lung ultrasound confirmed pulmonary edema (B lines). In comparison to the previous study, 11/11/2020, there has been a significant interval deterioration of left ventricular systolic function (previous EF 80%), and there is a new large apical wall motion abnormality.

The rhythm is indeed irregularly irregular, so atrial fibrillation must be considered. Sinus with multifocal PACs 3. GET a 12-lead!

In the context of today's case — these P waves are diagnostic of RAE = P Pulmonale ( See ECG Blog #75 ) and almost certain associated pulmonary hypertension. Retrospectively — I interpret this 1:1 retrograde conduction as diagnostic of a reentry SVT rhythm as the etiology of the initial tachycardia.

Smith interpretation: This is highly likely to be due to extreme right heart strain and is nearly diagnostic of pulmonary embolism. It is of course pulmonary embolism. No d-dimer or CT pulmonary angiogram was done when they discovered that she had normal coronary arteries. What is the clear diagnosis and reason for arrest?

The ECG and long lead II rhythm strip in Figure-1 — was obtained from a COVID positive patient with persistent tachycardia not responding to Diltiazem. Figure-1: The initial ECG — obtained from a patient with persistent tachycardia. ( Hypoxic injury ( from pneumonia or other acute pulmonary complication ).
