An instrument for recording the potential of the electrical currents that traverse the heart.

electrocardiograph

(ĭ-lĕk′trō-kär′dē-ə-grăf′)
n.
An instrument used in the detection and diagnosis of heart abnormalities that measures electrical potentials on the body surface and generates a record of the electrical currents associated with heart muscle activity. Also called cardiograph.

electrocardiograph (ECG)

[-kär′dē·əgraf′]
a device used for recording the electrical activity of the myocardium to detect transmission of the cardiac impulse through the conductive tissues of the muscle. Electrocardiography allows diagnosis of specific cardiac abnormalities. Leads are affixed to certain anatomical points on the patient's chest, usually with an adhesive gel that promotes transmission of the electric impulse to the recording device. electrocardiographic, adj.

(ĕ-lek'trō-kahr'dē-ō-graf)
An instrument for recording the potential of the electrical currents that traverse the heart.

electrocardiograph

An instrument consisting of a series of electrical cables (leads) with a lead-switching device, a high-gain, low-noise, balanced differential amplifier and a moving coil rotary transducer that converts the amplified signal into a varying trace on a calibrated strip of moving paper. The leads are connected to low-resistance contacts on the chest of the subject and the input to the device is derived from the minute electrical currents that flow towards and away from them as a result of the heart's contractions and relaxations.

Electrocardiograph (ECG, EKG)

A test of a patient's heartbeat that involves placing leads, or detectors, on the patient's chest to record electrical impulses in the heart. This test will produce a strip, or picture record of the heart's electrical functioning.

Patients also had 24-hour, continuous 12-lead ECG recordings (Holter monitors [HM]), a commonly-used method for AF surveillance, at 30 and 60 days post-procedure.
The patients underwent: standard 12-lead ECG and SA-ECG in the Functional Exploration Laboratory of the Pathophysiology department of the "Victor Babes" University of Medicine and Pharmacy, using a Siemens Megacart electrocardiograph.
A different approach to recording a 12-lead ECG is to make use of the EASI lead system (8) where 4 electrodes are placed on the torso at A (mid axillary line at level of V6), E (sternum at level of 5th intercostal space), I (mid axillary line at level of V6R) and S (sternum below the sternal notch).
Performing a 12-lead ECG is traditionally taught in a laboratory setting and requires a high faculty-to-student ratio to allow for closely monitored practice.
The smartphone-assessed heart rate is just as accurate as the clinically measured heart rate, with sensitivity exceeding 99% for QRS detection (and thus R to R intervals), putting it on par with the 12-lead ECG, according to Dr.
3%) was awarded an additional point for ST-elevation in right-sided leads without ST-depression on 12-lead ECG increasing the TIMI score from 6 to 7.
During a recurrence of the cardiac rhythm change, a 12-lead ECG was obtained (not shown) and pacemaker spikes were notable, indicating that the first change in cardiac rhythm seen above is due to ventricular pacing.
eRT will provide comprehensive site support and 60 units of 12-lead ECG recording equipment, which is designed to facilitate the collection of cardiac safety data that are subsequently provided to eRT for analysis.
Spacelabs will also highlight Sentinel, a cardiology information management system that integrates reports from Spacelabs' entire range of noninvasive diagnostic cardiology solutions - Holter monitoring, ambulatory blood pressure monitoring, 12-lead ECG, and ECG stress testing - then organizes and stores this data in a central networked database for fast, easy access.
