Pulmonary embolism; A lung illustration depicting a pulmonary embolism as a thrombus (blood clot) that has travelled from another region of the body, causes occlusion of the pulmonary bronchial artery, leading to arterial thrombosis of the superior and inferior lobes in the left lung: Specialty: Hematology, cardiology, pulmonology, Emergency ...
On an electrocardiogram (ECG), there are multiple ways RV strain can be demonstrated. A finding of S1Q3T3 [b] is an insensitive [10] sign of right heart strain. [11] It is non-specific (as it does not indicate a cause) and is present in a minority of PE cases. [12] It can also result from acute changes associated with bronchospasm and ...
Pulmonary hypertension Mitral stenosis Pulmonary embolism Congenital heart disease Arrythmogenic right ventricle cardiomyopathy Fascicular Block: Light-headedness Fainting Palpitations [3] Hereditary bundle branch block Pre-excitation Syndromes: Asymptomatic Wolff-Parkinson-White [4] Other causes: Variable Ectopic ventricular beats
Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax. Other causes include abdominal compartment syndrome, Hiatal hernia, severe aortic valve stenosis, and disorders of the aorta. Constrictive pericarditis is a rare cause.
Kussmaul sign suggests impaired filling of the right ventricle due to a poorly compliant myocardium or pericardium. This impaired filling causes the increased blood flow to back up into the venous system, causing the jugular vein distention (JVD) and is seen clinically in the internal jugular veins becoming more readily visible.

PH is broadly split into five categories by the World Health Organization, based on the underlying cause. The incidence of RVH varies between the groups. Common causes of PH include chronic obstructive pulmonary disease (COPD), pulmonary embolism, and other restrictive lung diseases. RVH often occurs as a result of these disorders.
The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved [1]), however most of the time, the right ventricle adjusts to an overload in chronic pressure.
cardiac causes, pulmonary causes and; non-pulmonary and non-cardiac causes. Considered physiologically, pulsus paradoxus is caused by: [citation needed] decreased right heart functional reserve, e.g. myocardial infarction and tamponade, right ventricular inflow or outflow obstruction, e.g. superior vena cava obstruction and pulmonary embolism, and
