Article Abstract
We present an artefactual ECG created by a digital ECG-recording machine, caused by deletion of the first 80 ms of the QRS complex immediately following the pacing spike in a patient with complete atrio-ventricular block, biventricular pacing and chronic atrial fibrillation. The artefact was mistaken for inferior ST elevation myocardial infarction and the patient underwent unnecessary urgent coronary angiogram. We are not aware of this particular artefact pattern being previously reported in the literature.

A 71-year-old black male with a history of hypertension, dyslipidemia, type 2 diabetes, history of bladder cancer status-post resection now in remission, history of multiple transient ischemic attacks, and coronary artery disease (CAD) presented with non-exertional substernal chest pain radiating to the left arm, accompanied by shortness of breath and nausea. Initial evaluation revealed elevated troponins and nonspecific electrocardiogram changes, consistent with non-ST elevation myocardial infarction. Coronary angiography demonstrated severe multivessel disease, including critical left main stenosis.

Background And Aims: Cold weather is associated with an increased risk of cardiovascular events, but its impact on culprit plaque characteristics in ST-segment elevation myocardial infarction (STEMI) remains unclear.
Methods: This study included 647 STEMI patients who underwent optical coherence tomography (OCT) to assess untreated culprit lesions. Participants were grouped based on ambient temperature on the day of admission or mean ambient temperatures over the preceding 7-, 14-, 21-, and 28-day periods.
Effect of ECMO Flow Variations on Pulmonary Capillary Wedge Pressure in Patients With Cardiogenic Shock.

Background: The hemodynamic effects of femoro-femoral venoarterial (VA) extracorporeal membrane oxygenation (ECMO) on pulmonary capillary wedge pressure (PCWP) remain poorly defined. High ECMO flow is believed to increase PCWP and the risk of pulmonary edema; yet, supporting in vivo physiological data are lacking.
Objectives: The purpose of this study was to evaluate the impact of incremental femoro-femoral VA-ECMO flow variations on PCWP, hemodynamic, and echocardiographic parameters in patients with cardiogenic shock during the early phase of VA-ECMO support, after stabilization.
