What does the QRS complex of an ECG represent? What are the different types of rhythms on an EKG exam? What does an electrocardiogram measure? a. Sound waves created by the closing of heart valves b. The volume of blood moving through the heart chambers c. The force of muscle contraction...
This training series will provide an overview of the physiology behind ECG as well as the key functional blocks and specifications needed to measure it.
ECG records the electrical activity generated by heart muscle depolarizations (a negative change in the electric charge), which propagates as pulsating electrical waves towardsthe skin. Although the amount of electricity is in fact very small, it can be picked up reliably with ECG electrodes attach...
What equipment is used to measure heart rate? What is the T wave in an ECG? What is cardiac dysrhythmia? What does epinephrine do during cardiac arrest? What does the heart do? What is a vestibular lesion? What is vestibular stimulation?
An ECG makes electrical impulses and conduction visible and is the single most important noninvasive monitoring parameter of the heart. However, it does not give any data on myocardial function or contractility. Severely disturbed myocardial function such as decompensation of the heart can be detected...
