|
Bradycardia
|
The SA node discharges impulses more slowly than normal and conduction continues in a normal fashion through the rest of the heart.
|
|
|
Premature Ventricular Contractions (PVCs)
|
An ectopic foci in the ventricles discharges an impulse before the SA node.
|
|
|
Types of Premature Ventricular Contractions
|
- Unifocal PVC – Better to have since there is only one site that is irritated in the ventricle
- Frequent PVCs - Several PVCs in a row - Treatment for PVCs |
|
|
Ventricular Tachycardia
|
An ectopic foci in the ventricles becomes the pacemaker of the heart.
Ventricular Tachycardia Treatment for VT with a pulse |
|
|
Treatment of VF or pulseless VT
|
- Check for responsiveness, activate the EMS system (call a code), call for a defibrillator
- Open the airway, check for breathing, begin ventilations, check for pulse, begin compressions (ABC plus D) - As soon as a defibrillator is available-defibrillate - Check for a pulse - If the pulse is absent and there is no change in rhythm-defibrillate again - Check for pulse - If pulse is absent and there is no rhythm change-defibrillate - Start an IV and begin to administer meds (CPR should be continued) - Give epinephrine IV push (may give every 3-5 minutes) - Defibrillate - If patient remains in rhythm, administer Amiodarone IV followed OR |
|
|
Asystole
|
No electrical activity is happening. No pacemaker is firing
|
|
|
Pulseless Electrical Activity (PEA)
|
- The patient has electrical activity on the monitor but no heartbeat
Treatment for PEA and asystole - Check for responsiveness, activate EMS (call a code), call for defibrillator - Begin CPR - Start and IV and administer Epinephrine IVP (Epinephrine may be repeated every 3-5 minutes) - Atropine IV - Consider causes of PEA such as hypovolemia, hypoxia, acidosis, potassium imblances, hypothermia, overdose, cardiac tamponade, tension pneumothorax, acute coronary syndrome, PE |
