The concertina effect (or accordion effect) in Wolff-Parkinson-White (WPW) syndrome refers to the dynamic, beat-to-beat variation in the degree of ventricular pre-excitation visible on a single ECG rhythm
The ALL-RISE trial was a large-scale, international, randomized, non-inferiority study designed to evaluate whether CathWorks FFRangio (an angiography-derived fractional flow reserve tool) performs as well as conventional pressure
While mitral valve prolapse (MVP) is generally a benign condition with an excellent overall prognosis, a specific, albeit rare, subset of patients exhibit what is termed the Arrhythmic
The Bix Rule is a high-yield diagnostic principle in electrocardiography used to unmask atrial flutter or atrial tachycardia with 2:1 atrioventricular (AV) block. It is named after Dr.
The cause of exercise-associated muscle cramps (EAMC) has been heavily debated in sports medicine. While traditionally blamed on dehydration or a lack of electrolytes, modern scientific consensus points
When assessing a hemodynamically unstable patient for suspected acute pulmonary embolism (PE) — particularly when CTPA is precluded — identifying acute right heart strain is critical. The right
The management of atrial fibrillation (AF) in the setting of heart failure (HF) has undergone a major paradigm shift. The historical approach of rate control as a purely
Assessing right ventricular (RV) function via echocardiography is uniquely challenging due to the chamber’s complex, crescentic geometry and its position immediately behind the sternum. Because no single two-dimensional
A complete Transthoracic Echocardiogram (TTE) relies on four primary acoustic windows to visualize the heart’s anatomy and hemodynamics. 1. Parasternal Long-Axis View (PLAX) The PLAX view is typically
The Bezold-Jarisch reflex (BJR) is an inhibitory cardiovascular reflex originating from receptors within the heart itself. When triggered, it causes a classic triad of bradycardia (slow heart rate),
