EKG 6 Leads
An EKG helps your doctor diagnose and monitor many heart problems. These commonly include a heart attack, cardiac arrhythmias (abnormal heartbeats), and coronary artery disease (narrowing of the coronary arteries).
A Holter monitor is a type of heart monitor that records the heart’s activity over 24 or 48 hours. It is very useful when a patient has an irregular heartbeat or complains of heart palpitations, but an EKG was not able to detect anything.
