She also has a hx of paroxysmal atrial fibrillation and is on oral anticoagulant treatment. She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. The ECG was interpreted as showing atrial flutter with 2:1 conduction. The ECG below was recorded. What is your assessment?

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.

The rhythm is indeed irregularly irregular, so atrial fibrillation must be considered. There are 5 other rhythms that are irregularly irregular , though atrial fibrillation is by far the most common: 1. Multifocal Atrial Tachycardia 2. Sinus with multifocal PACs 3. Sinus with multifocal PVCs 4.

If the patient has Abnormal Vital Signs (fever, hypotension, tachycardia, or tachypnea, or hypoxemia), then these are the primary issue to address, as there is ongoing pathology which must be identified. Negative predictors included dementia, pacemaker, coronary revascularization, and cerebrovascular disease. orthostatic vitals b.

How does a pacemaker accomplish RBBB morphology? Quick aside on device terminology (feel free to skip): A "single chamber" pacemaker is a device with only one lead. A "dual chamber" pacemaker is a device with an atrial lead and a ventricular lead. So the most likely rhythm in ECG 1 is ectopic atrial tachycardia.
