Term
|
Definition
| Denotes atrial depolarization (when atria contract and squeeze blood into the ventricles) |
|
|
Term
|
Definition
| no relationship between the atria and ventricular rhythms- like two separate EKGs stuck together, normal equally spaced p waves, equally spaced wide QRS complexes |
|
|
Term
|
Definition
|
|
Term
|
Definition
| Denotes ventricular repolarization (when the ventricles get "charged" and ready to depolarize- an inactive period) |
|
|
Term
|
Definition
| all intervals normal, rate greater than 100 |
|
|
Term
|
Definition
| all intervals are normal, rate is less than 60 |
|
|
Term
| 2nd degree AV block type 2 |
|
Definition
| p-r intervals are normal but a QRS is dropped in a regular pattern |
|
|
Term
|
Definition
| SVT comes and goes in a rhythm it is not the underlying rhythm |
|
|
Term
|
Definition
| early beat that has a p wave shaped differently than the p waves in the rest of the rhythm (abnormal beat) |
|
|
Term
|
Definition
| Wide, bizzare complexes, no intervals, very fast but difficult to measure, Torsades de Pointes type of VT- caused by deficient Magnesium |
|
|
Term
|
Definition
|
|
Term
|
Definition
| no p waves or inverted p waves with rate of 60-100 |
|
|
Term
|
Definition
| nothing but a squiggly line |
|
|
Term
|
Definition
| Abnormal beat, wide bizarre complex in the middle of a rhythm, unifocal - all PVC's are same shape, multifocal- all look different, Bigeminy- when every other beat is PVC, Trigeminy- ever third beat PVC |
|
|
Term
|
Definition
| no p waves (saw-tooth pattern) regular rate 80's to 100's |
|
|
Term
|
Definition
| no P waves (just a squiggly line), irregular, rate 120's to 180's |
|
|
Term
| AV block 2nd degree (Wenkebach) |
|
Definition
| p-r interval progressivley lengthens until a QRS is dropped |
|
|
Term
|
Definition
| p-r interval greater than .20 |
|
|
Term
|
Definition
| early beat with either no or an inverted p wave |
|
|
Term
|
Definition
| all intervals are normal, rate 60-100 |
|
|
Term
|
Definition
| no p waves or inverted p waves, p wave can come after QRS, rate 40-60 |
|
|
Term
|
Definition
| no p waves or inverted p waves, with a rate greater than 100 |
|
|
Term
|
Definition
| Denotes ventricular depolarization (when ventricles contract and send blood to the lungs and out the aorta to the body) |
|
|
Term
|
Definition
| rate is very fast 150-250 difficult to distinguish p waves and t waves because of the rapid rhythm, QRS usually narrow, rhythm is regular |
