Ventricular arrhythmias during exercise can be documented in congenital long QT syndromes as well as in catecholaminergic polymorphic ventricular tachycardia. QT prolongation and the occurrence of ventricular arrhythmias with exercise are another important aspect of exercise testing in children.

Follow-up contained regular visits at our outpatient clinic at 1, 3, 6, and 12 months including 7-day Holter electrocardiograms. After a blanking period of 6 weeks, recurrence of any atrial arrhythmia was documented in 26 patients (52%). Patients were mainly suffering from long-standing persistent AF (mean AF duration 50.30 ± 54.28

Meyers, Weingart and Smith published their OMI Manifesto — in which they extensively document the critically important concept that management of acute MI by separation into a “STEMI” vs “non-STEMI” classification is an irreversibly flawed approach.

Of course, the ECG after the cath was very much changed.

The diagnosis was made based on classic findings of inflammation on an electrocardiogram associated with acute chest pain. The case reports Case 1 involves a 26 year old man who developed pericarditis after the Pfizer vaccine. Pericarditis, an inflammation of the sac the heart lives in, developed about 7 days after the Pfizer vaccine.

A previously healthy 45-year-old man was referred to the emergency department post–cardiopulmonary resuscitation after documented ventricular fibrillation (VF). A 12-lead electrocardiogram (ECG) was performed (Figure 1). His blood pressure was 80/40 mm Hg. There was no family history of sudden death.

Abnormal Electrocardiogram (ECG): Defined (San Fran syncope rule) as any new changes when compared to the last ECG or presence of non-sinus rhythm. Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful. Abnormal ECG – looks for cardiac syncope.

Thus, Brugada is the likely diagnosis _ A very nice explanation of this is given in the document quoted below on current ECG criteria for Brugada pattern. Fever not only unmasks a Brugada-type electrocardiogram (ECG) but also increases the risk of ventricular tachyarrhythmias such as ventricular fibrillation (VF) or sudden cardiac death.

The emergency physician does cautiously (correctly) note that the ECG meets STEMI criteria in V3 and V4, but goes on to document absence of ACS symptoms. Artificial intelligence (AI) algorithms show promise to improve electrocardiogram (ECG) interpretation. The patient ruled out for MI with serial troponin testing.
