EKG and Defibrillation Flashcards
indications for cardiac monitoring
monitor HR, basic rhythm, diagnose arrhythmias, myocardial ischemia, and prolong QT interval
cardioversion used for what conditions
- atrial fibrillation
- atrial flutter
- supraventricular tachycardia
- stable or unstable ventricular tachycardia with a pulse
3 lead cardiac monitoring provides
rate and basic rhythm, and can be portable or bedside
5 lead cardiac monitoring provides
more views of heart and complex rhythm interpretation
3 lead monitoring leads placed wear
1 - 4th intercostal right MCL
2 - below left clavicle
3 - below axilla
5 leads monitoring leads placed wear
1 and 2 - below clavicles
3 - 4th intercostal right MCL
4 and 5 - right left abs
continuous ECG monitoring, how many leads
1 or 2 leads, may also be connected to telemetry, includes beside monitor
indications for ECG
- over 50 routine
- chest pain, angina, cardiac-abnormalities with fainting, syncope, palpitations
- hx of CAD, MI, heart failure, cardiac problems
- shock/trauma
how many views of heart do you get with 12 lead ECG
12 views of heart wth 10 electrodes
when an electrical shock is delivered at the exact time the persons own electrical conduction system is depolarizing
synchronized cardioversion
during which wave does synchronized cardioversion deliver the shock
synced with the R wave
how many joules for synchronized cardioversion
100-200 joules
desired outcomes of synchronized cardioversion
- terminate tachycardia
- restoration of sinus rhythm, that maintains cardiac output and vital signs
adverse outcomes of synchronized cardioversion
superficial skin burns, asystole, bradycardia, ventricular fibrillation
defibrillation used when
for chaotically beating heart, non-perfusing rhythm, and no pulse, BP, cardiac output
