He had a triage ECG at time zero: Here is the computer interpretation (Normal) This was the Veritas algorithm. What do you think? This ECG is DIAGNOSTIC of acute LAD Occlusion. The T-waves are hyperacute, but most important, the minimal ST Elevation is accompanied by Terminal QRS Distortion , or at least nearly so.

This two-lead rhythm strip shows a normal sinus rhythm at about 63 bpm. The P waves are regular. After the sixth P-QRS, there is a non-conducted P wave. The normal rhythm then resumes. The two most common reasons for a non-conducted P wave in the midst of a normal sinus rhythm are 1) non-conducted PAC, and 2) Wenckebach conduction. The first is easy to rule out.

Background Pulse pressure (PP), a raw index of arterial stiffness, is inversely related to coronary microvascular function, even among patients with non-obstructive coronary artery disease (CAD), as per non-invasive studies. We aimed to determine whether invasive aortic PP is associated with coronary microvascular endothelial dysfunction (CMED) and/or coronary microvascular endothelial independent dysfunction (CMEID) in patients with non-obstructed CAD.

Objectives To investigate the reliability and agreement of hand-held ultrasound devices (HUDs) compared with conventional duplex ultrasound (HIGH) in examination for carotid stenosis in patients with suspected transitory ischaemic attack (TIA) or ischaemic stroke. Methods Cardiologists, experienced in carotid ultrasound, examined patients admitted to a community hospital with suspected stroke or TIA.

Objectives To understand the patient and hospital level drivers of the variation in surgical versus trascatheter aortic valve replacement (SAVR vs TAVR) for patients with aortic stenosis (AS) and to explore whether this variation translates into differences in clinical outcomes. Background Adoption of TAVR has grown exponentially worldwide. Notwithstanding, a wide variation in TAVR rates has been seen within and between countries and in some jurisdictions AS is still primarily being managed by S
