A cardiologist diagnoses and treats diseases of the heart and blood vessels. Hypertension, heart failure, rhythm disorders and coronary artery disease are the main areas.
If chest pain radiates to your arm or jaw, or comes with shortness of breath or fainting, call emergency services immediately. For mild, brief pain, see a cardiologist the same day.
Readings above 140/90 mmHg at rest are considered hypertension. Diagnosis requires repeated measurements across at least 2 separate visits.
An ECG records the heart's electrical activity (rhythm, conduction). An echocardiogram uses ultrasound to show heart structure and valve function. They provide different information.
