| The average pressure over the entire cardiac cycle [(2 x diastolic + systolic)/3] is known as... | Mean Arterial Pressure (MAP) |
| These affect automaticity (the rate at which electricity moves through the heart)... | Dromotropes |
| Chronotropes affect this... | heart rate |
| Inotropes affect this... | contractility |
| Use this tip to determine the normal systolic blood pressure for children aged 1-10... | Add twice their age to 90mmHg |
| Use this tip to determine systolic hypotension in children aged 1-10... | Add twice their age to 70mmHg |
| This drug, used to treat bradycardia, is to be used with caution in cases of cornary ischemia and MI and is unlikely to be effective after cardiac transplantation, type II second-degree heart block, or third degree heart block... | Atropine |
| This drug, given for bradycardia, is a positive inotrope, dromotrope, and chronotrope | Epinephrine |
| This drug can be effective in increasing heart rate at doses between 2-10 mcg... | Dopamine |
| Pacemaker therapy is used when this system is inadequate to sustain a heart rate... | the heart's intrinsic pacemaking system |
| This type of pacing in the ED uses large electrodes placed on the skin, one on the back at midthoracic level of the spine and a second on the front at the chest lead level of V3... | External (transcutaneous) |
| This type of pacing done in the ED involves threading a catheter electrode into the right atrium or ventricle via the subclavian, internal jugular, brachial, or femoral vein... | Transvenous |
| Concerning pacemaker settings, this is how often the pacemaker fires... | heart rate |
| Concerning pacemaker settings, this is the strength of the pacemaker impulse... | pacemaker output |
| Concerning pacemaker settings, this is the degree with which the pacemaker senses intrinsic impulses... | sensitivity |
| In troubleshooting implanted pacemakers, possible causes of this problem may be battery failure, lead problem (lead fracture or fractured lead insulation), or oversensing... | Failure to output |
| In implanted pacemaker troubleshooting, possible causes of this problem may be failing battery, lead issue (lead fracture, dislodgement, or fractured lead insulation), exit block (from ischemia/infarction, hyperkalemia or class III antiarrhythmic drugs)... | Failure to capture |
| This should be done while the failure to capture problem is being identified... | temporary pacing |
| The cause of this pacemaker problem can be muscular activity or outside interference (MRI, electrocautery, digital cellular phones)... | Oversensing |
| This should be done to the pacemaker for an oversensing problem... | magnet application |
