🟠 Calculating Shunt Fraction (Qp/Qs) Using Echocardiography

…Qs). This measurement is pivotal in diagnosing and managing congenital or acquired cardiac shunts, such as atrial septal defects (ASD), ventricular septal defects (VSD), and…

Post-Infarction Mechanical Complications: Ventricular Septal, Free-Wall, and Papillary Muscle Rupture

…STEMI). The principal lesions are: Ventricular septal rupture (VSR), producing an acute left to right shunt. Ventricular free wall rupture, producing haemopericardium and cardiac tamponade…

ST-Elevation Myocardial Infarction Complicated by Cardiogenic Shock

…mechanical complications—particularly ventricular septal defect (VSD) and papillary muscle rupture with acute severe mitral regurgitation—predominant right ventricular (RV) infarction, cardiac rupture with tamponade…

Isoprenaline and Dopamine Infusions for Bradycardia

…BBB) or an intraventricular conduction defect. In severe cases, bradycardia may progress to hemodynamic instability, presenting as shock or cardiac arrest manifesting as bradyarrhythmic arrest…

Left Bundle Branch Block: ECG criteria and clinical implications

…peak biomarker levels, compared to those without such conduction defects [12]. Sudden Cardiac Death (SCD) : In patients with a low ejection fraction, syncope is considered…

Hypertrophic Cardiomyopathy (HCM) & Hypertrophic Obstructive Cardiomyopathy (HOCM)

…cardiac death. Therefore, current screening recommendations for athletes emphasize on measures to detect hypertrophic cardiomyopathy. Hypertrophic cardiomyopathy is the most common cause of sudden cardiac…

Ultrasound (echocardiography) in cardiac arrest and resuscitation

…low. Notably, specificity increases when the septum bulges into the left ventricle (i.e. septal bulging ). Bedside echocardiography allows for immediate recognition of tamponade. Typically…

Left Ventricular Segments for Echocardiography and Cardiac Imaging

…However, due to varying strengths, limitations and clinical applications of these modalities, the definitions of cardiac planes, ventricular segments, and coronary arterial territories evolved differently…

Tricuspid regurgitation (TR/TI)

…the right atrium. It normally consists of three leaflets (anterior, posterior and septal leaflet). The leaflets are attached to the subvalvular apparatus, consisting of the…

ECG manifestations of left main coronary artery (LMCA) occlusion and critical stenosis

…cardiogenic shock, malignant ventricular arrhythmias, or sudden cardiac death. The resulting extensive ischemia causes immediate myocardial stunning (akinesia) and electrical instability. Fewer than 1% of…
