Cardiologists (heart doctors) are medical doctors who specialize in diagnosing and treating disorders of the heart.Cardiologists diagnose and treat heart and blood vessel problems using a combination of physical examination, symptom review and medical testing. Some cardiologists work in private practice centers as consultants to patients' general care practitioners, while others work for universities as researchers and teachers. As part of their practice, cardiologists may perform or recommend procedures like echocardiograms, exercise tests and cardiac catheterizations.
• Cardiology can be a high pressured job, involving long hours and weekend work - although private consultants have more control over their hours. • Cardiologists usually work in small private offices or clinics, and are often assisted by a small staff of nurses and administrative personnel. • Frequent travel between their office and their appointed hospital is required, as is being 'on call' in case of an emergency.
