Answer |
| 4-Lead ECG |
An ECG that uses 4 leads attached to the pts skin; these include the limb leads |
| 12-Lead ECG |
An ECG that uses 12 leads attached to the pts skin; these include the limb leads and chest leads |
| arrhythmia |
Abnormal rhythm of the heart, sometimes called a dysrhythmia |
| asystole |
The complete absence of any electrical cardiac activity, appearing as a straight or almost straight line on an ECG strip. |
| cardiac monitoring |
The act of viewing the electrical activity of the heart thru the use of an ECG machine or cardiac monitor |
| Chest leads |
the leads that are used only with a 12-lead ECG and must be placed exactly; includes leads V1, V2, V3, V4, V5, and V6 |
| ECG |
Electrocardiogram; an electronic tracing of the heart's electrical activity thru leads, which originate in the electrocardiograph machine and contain electrodes that attach to the pts chest and/or limbs |
| Electrical conduction system |
A network of special cells in the heart thru which an electrical current flows, causing contractions of the heart that produce pumping of blood. |
| Limb leads |
the four leads used with a 4-lead ECG; placed on or close to the right arm, left arm, right leg, and left leg |
| normal sinus rhythm |
A rhythm that has consistent P waves, consistent P-R intervals, and a regular heart rate between 601 and 100 beats/min |
| sinus bradycardia |
A rhythm that has consistent P waves, consistent P-R intervals, and a regular heart rate that is less than 60 beats/min |
| sinus rhythm |
A rhythm in which the SA node acts as the pacemaker. |
| sinus tachycardia |
A rhythm that has consistent P waves, consistent P-R intervals, and a regular heart rate that is more than 100 beats/min. |
| ventricular fibrillation |
A rapid, completely disorganized ventricular rhythm with chaotic characteristics, no specific pattern, and no discernable P, QRS, or T waves |
| ventricular tachycardia |
The presence of three or more abnormal ventricular complexes in a row with a rate of more than 100 beats/min. |
