Cardiology Glossary

The degree of myocardial stretch at end-diastole, reflecting venous return and ventricular filling pressure.

Percutaneous transluminal coronary angioplasty, a catheter-based procedure to open blocked coronary arteries.

An abnormal decrease in systolic blood pressure of more than 10 mmHg during inspiration, indicating impaired venous retu...

The presence of additional spikes or notches within the QRS complex on electrocardiogram, indicating abnormal ventricula...

Heart rate-corrected QT interval on ECG, representing ventricular depolarization and repolarization time.

Tissue damage that occurs when blood supply returns to tissue after ischemia, paradoxically worsening injury.

Invasive procedure measuring pressures in the right side of the heart and pulmonary circulation.

A severe type of heart attack characterized by complete blockage of a coronary artery, identified by specific ECG change...

Abnormal narrowing of a heart valve or blood vessel that restricts blood flow.

Echocardiographic imaging performed during or immediately after cardiac stress to detect inducible ischemia.

Transient loss of consciousness due to cerebral hypoperfusion, requiring careful differential diagnosis documentation in...

The contraction phase of the cardiac cycle when blood is pumped from the heart chambers.

Temporary heart condition mimicking myocardial infarction, often triggered by emotional or physical stress.

Tricuspid annular plane systolic excursion, an echocardiographic measurement of right ventricular systolic function.

Transcatheter aortic valve implantation, a minimally invasive procedure to replace the aortic valve without open-heart s...

Transesophageal echocardiography, an imaging technique using an ultrasound probe inserted into the esophagus for detaile...

A palpable vibration on the chest wall caused by turbulent blood flow, typically from severe valve disease or shunt.

Treatment using clot-dissolving medications for acute cardiovascular conditions, with strict timing and contraindication...

A standardized grading system (0-3) for assessing coronary blood flow during angiography.

A protein released into the blood when heart muscle is damaged, serving as a biomarker for myocardial injury.

A breathing technique involving forced expiration against a closed airway, used diagnostically in cardiac examinations.

Backward flow of blood through a heart valve due to incomplete valve closure, also called valve insufficiency.

A medication that causes vasoconstriction to increase blood pressure and vascular resistance.

Sudden constriction of coronary arteries that can reduce blood flow and cause angina or myocardial infarction.
