Gardner Treadmill Protocol Gardner Treadmill Protocol, also known as Gardner-Skinner Protocol was described in 1991 [1]. It is used mainly in the evaluation of peripheral arterial disease. The seminal article evaluated the effect of handrail support on claudication distance. Handrail support reduces energy cost of treadmill walking, and can affect claudication distance and hemodynamic responses in persons with peripheral vascular disease.

The three images beneath one and other are consecutive rhythm strips each 10 seconds long. The patient was on telemetry due to acute MI. Can you correctly describe what's going on in this interesting rhythm strip?

Introduction Atrial fibrillation (AF) is associated with a fivefold increased risk of stroke. Oral anticoagulation reduces the risk of stroke, but AF is elusive. A machine learning algorithm (Future Innovations in Novel Detection of Atrial Fibrillation (FIND-AF)) developed to predict incident AF within 6 months using data in primary care electronic health records (EHRs) could be used to guide AF screening.

Abstract Aims Patients with heart failure (HF) and mildly reduced ejection fraction (HFmrEF) and preserved ejection fraction (HFpEF) are often treated with calcium channel blockers (CCBs), although the safety of CCBs in these patients is uncertain. We aimed to investigate the association between CCB use and clinical outcomes in patients with HFmrEF/HFpEF; CCBs were examined overall, as well as by subtype (dihydropyridine and non-dihydropyridine).
