While an ECG is a superior diagnostic tool, experienced practitioners are witness to false positive and false negative ECGs. A false positive ECG occurs when

The EASI (TM) lead system uses a 5 cable connector to estimate a 12 lead ECG. In an effort to reap the advantages of 12

Electrocardiogram; also called an EKG; a representation of electrical voltage measured across the chest over a period of time. 1. Six Second ECG Guidebook (2012),

An ECG is composed of a series of waves and lines usually ordered into some repeatable pattern. The waves and lines are displayed on either

Usually, the first word of a rhythm is the location of the initiating impulse. This is followed by a descriptor of the rate – bradycardia,

An ECG is a graphical display of electrical energy generated by the heart over time. ECG graph paper records this cardiac electrical activity, printing at

Table 6.5 provides a non-exhaustive list of cardiac conditions that are associated with a variety of abnormal ECG waveforms. Arriving at a useful interpretation of

A depolarizing wave that originates anywhere outside of the SA node. 1. Six Second ECG Guidebook (2012), T Barill, p. 196

A depolarizing wave that originates anywhere outside of the SA node. Atrial Ectopics – Premature Atrial Complex (PAC) Early QRS complexes (usually narrow) make the

Dr. Einthoven was a physiologist, who in the late 1800s, first established the 3-lead cardiac monitoring system; the three lead system maps the electrical workings

The percentage of blood volume ejected from the ventricle; for example, if blood volume in the left ventricle at the end of diastole is 100

Electrocardiogram; also called an ECG. 1. Six Second ECG Guidebook (2012), T Barill, p. 196

The direction of an average (mean) vector is called the electrical axis. The overall direction of ventricular depolarization is called the QRS axis. Many novice
