But if you have a family history of heart disease, your health care provider might suggest an electrocardiogram as a screening test, even if you have no symptoms. The American Heart Association doesn't recommend using electrocardiograms to assess adults at low risk who don't have symptoms.

Weakness, fatigue or a decline in ability to exercise.

Dizziness, lightheadedness or confusion.

You may need an ECG if you have any of the following signs and symptoms:

How well certain heart disease treatments, such as a pacemaker, are working.

Whether you have had a previous heart attack.

If blocked or narrowed arteries in the heart (coronary artery disease) are causing chest pain or a heart attack.

A health care provider might use an electrocardiogram to determine or detect:

Implantable loop recorder: A heart monitoring deviceĪn electrocardiogram is a painless, noninvasive way to help diagnose many common heart problems.

(16) In a study of patients with advanced heart failure who underwent pulmonary artery catheterization, Drazner et al compared impedance cardiography with invasive hemodynamic measurements. (15) Impedance cardiography provides noninvasive, readily available, and continuous measurements of cardiac output and other hemodynamic parameters such as systemic vascular resistance. (14) Wagner's company, which produces a range of high-technology devices, including cardiographs and patient monitors, expects computers to revolutionize the way medical device manufacturers support customer training efforts.

emergency departments use the four cardiographs that the Audicor CE runs with. (12) They may be assisted by cardiographers, and work closely with other technical and nursing staff. (11) Specifically, factors related to patients such as ventricular function and valve function were examined to determine if advanced heart failure and/or valve regurgitation affected the accuracy of impedance cardiography. (10) The department has a team of dedicated cardiographers who provide an ECG and ambulatory monitoring service across the whole hospital site. (9) A significant number of health workers - including nurses, radiographers, cardiographers and labourers - tested positive when they were scanned last week for thyroid nodules. (8) After the leads for impedance cardiography were applied, we were unable to accurately collect and record bioimpedance data from 4 patients. (7) His ears didn't pick up anything but the digital tick of the cardiograph, not the plodding footsteps or melodic dry thumps of a cane.

(6) A cardiograph would be able to record my heart movements accurately and then you'd have a concise visual aid.

(5) The gradient profile of the hills provided in my cycling guide looks suspiciously like the cardiograph reading of a 36-year-old having a heart attack, but I am not deterred. (4) Inovise went to four outside firms for help creating its Audicor cardiograph expansion system. (3) My son is now a house husband and part-time senior cardiograph technician working between two hospitals looking after two children. (2) The hospital issued a press release saying Lee is recovering well and that a physical examination and cardiograph showed his condition was normal. (1) The silence was broken only by the constant beep of the cardiograph, the electrical noise humming out every few seconds to indicate a resting, biologically functional heart resting inside of her battered ribcage.
