Interpreting the waves and detecting abnormalities: Typically, the heart conducts electricity in a pathway starting in the sinoatrial node (SA), our heart’s “natural pacemaker”, located in the wall of the right atrium. Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia. Usually does not exceed 160 bpm.

He has a pacemaker for an unknown arrhythmia reason, and has a hx of a PE but is not anti-coagulated currently. This is obviously diagnostic of inferior and lateral Occlusion Myocardial Infarction. The location of the infarct is clear, but that does not necessarily tell you what artery it is. It was central and constant.

He had previously undergone non‐contrasted head computed tomography (NCHCT) (magnetic resonance imaging (MRI) was unable to be performed secondary to pacemaker), which did not reveal strokes. Episodes always occurred after activity and only upon sitting. His initial computed tomography angiogram (CTA) of the head and neck was unremarkable.

Moreover, the improvement of care for patients with myocardial infarction has resulted in higher survival rates, but as a result, more patients suffer from heart failure. This can be achieved by introducing electrodes into the vascular system which are connected to a pacemaker with a resynchronization function.

The researchers were able to show that those who had been ill with COVID-19 could also suffer from heart rhythm disturbances, both in the form of so-called tachycardias , when the heart ha rate is high, and bradyarrhythmias , when the heart is slow so that a pacemaker is sometimes needed.

There are Q-waves in V1-V3 (myocardial infarction of indeterminate age). So I am skeptical that this term has any practical significance.
