|---|---|---|---|---|---|
| ECG / EKG | Electrocardiogram
🗑
|
||||
| SA node | Sinoatrial Node
🗑
|
||||
| AC interference | Artifact on an ECG tracing caused by electrical interference example/cell phone
🗑
|
||||
| P wave | represents atrial depolarization
🗑
|
||||
| PR interval | represents the time it takes for the electrical impulse to travel from the SA node to the AV node. Normal range is 0.12 to 0.20 seconds
🗑
|
||||
| QRS | representative of ventricular depolarization normal range for a QRS complex is 0.06-0.10 sec
🗑
|
||||
| QT interval | the time from the beginning of the QRS complex, representing ventricular depolarization, to the end of the T wave normal range 0.4-0.44 sec
🗑
|
||||
| T wave | represents ventricular repolarization
🗑
|
||||
| Artifact | Anything artificially produced on an ECG
🗑
|
||||
| Arrhythmia | Abnormal Rhythm of heart beat
🗑
|
||||
| Asystole | Absence of heart beat (Cardiac arrest)
🗑
|
||||
| Atrial Tachycardia | rapid heart rate, causing the P wave to be unidentifiable or hidden in the previous T wave
🗑
|
||||
| Baseline | Initial measurement for future comparing
🗑
|
||||
| Bradycardia | Slow heart rate, less than 60 bpm
🗑
|
||||
| Bundle of His | part of the electrical system of the heart, it transmits impulses from the AV node to the ventricles of the heart
🗑
|
||||
| Diastole | Relaxation of the heart
🗑
|
||||
| Precordial | Pertaining to the precordium, refers to the chest leads placed on the patient for ECG testing
🗑
|
||||
| Polarization | cardiac cells in a resting, negatively charged state
🗑
|
||||
| Purkinje fibers | networks of fibers that receive conductive signals originating at the AV node and simultaneously activate the left and right ventricles by directly stimulating the ventricular myocardium
🗑
|
||||
| Sinus Rhythm | Any cardiac rhythm in which depolarization of the cardiac muscle begins at the sinus node
🗑
|
||||
| Normal sinus rhythm | regular rate (60-100bpm) and rhythm seen on the ECG
🗑
|
||||
| Somatic Tremor | Interference/artifact throughout the ECG tracing, often caused by patient movement or shivering
🗑
|
||||
| Systole | The contraction of the heart
🗑
|
||||
| Tachycardia | Fast heart rate greater than 100 bpm
🗑
|
||||
| Wandering baseline | artifact on an ECG commonly caused by loose electrodes
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
