Rapid A Fib & A Flutter

Adult- Unstable (Hypotension)

A
  • Normal Saline: 1L. Assess lung sounds every 500mL.
  • If blood pressure stabilizes then administer Cardizem as indicated above.

Q

Bradycardia

Pediatric- Unstable

A

(Defined as a child with AMS and poor perfusion)
• OXYGENATION & VENTILATION: Ensure adequate oxygenation and ventilation first, as hypoxia is most likely to be the cause of the bradycardia.
• After oxygenation and ventilation of 1 minute for infants/children and 30 seconds for neonates (birth to 1 month), begin chest compressions if the heart rate remains below 60 BPM with signs of poor perfusion (AMS).
• Push Dose EPINEPHRINE
• If no response to Epinephrine, begin TRANSCUTANEOUS PACING. Begin pacing at 80 BPM and increase the rate as needed until the patient is hemodynamically stable. Start at 30 milliamps and Increase milliamps until electrical and mechanical capture is achieved.

Q

STEMI Alert Disqualifiers

Study These Flashcards
A

The following are STEMI mimics:
• QRS complexes greater than 0.12 (LBBB, Pacemaker, etc.)
• Left Ventricular Hypertrophy (LVH)
• Pericarditis
• Early Repolarization
• Less than 2mm of elevation with a Concave ST Segment (Smiley Face) Morphology

Left Ventricular Hypertrophy (LVH)
Take the largest negative deflection from the isoelectric line of VI and V2 (“S” wave), whichever is larger, and count the small boxes. Then take the largest positive deflection of V5 or V6 (“R” wave), whichever is larger, and add it to the total from VI or V2. If the result is greater than 35, your suspicion for LVH should be high.

CAUTION: DO NOT cardiovert wide complex tachycardias that are irregularly/irregular, as they are most likely to be A-Fib/A-Flutter with an aberrancy and would put the patient at risk for an embolic stroke. ECG features that favor a diagnosis of Ventricular Tachycardia • Precordial concordance –all chest leads point in the same direction (either positive OR negative) • Presence of capture beats or fusion beats • Absence of RS in all precordial leads • R to S > 100 ms in one precordial lead ECG features that favor a diagnosis of supraventricular origin • Normal R wave progression in the chest leads • Left bundle branch block or right bundle branch block pattern • Only slight widening of the QRS • Irregularly-irregular rhythm ALL REGULAR WCTs SHOULD BE TREATED AS V-TACH UNLESS PROVEN TO BE SUPRAVENTRICULAR!

12 LEAD ECG STABLE PVT * MAG SULFATE: 2g IV/IO, in 50 mL of Normal Saline - as per infusion protocol Unstable PVT * DO NOT DELAY DEFIBRILLATION TO ESTABLISH IV ACCESS! Sedation • ETOMIDATE: 10mg IV/IO. • DEFIBRILLATION: 200j ZOLL 360j LP • Magnesium Sulfate Infusion regardless of conversion. CAUTION: DO NOT cardiovert wide complex tachycardias that are irregularly irregular, as they are most likely to be A-Fib/A-Flutter with an aberrancy and would put the patient at risk for an embolic stroke. If defibrillation terminates the PVT and the patient returns to PVT, begin defibrillation at the last successful energy setting and increase as needed.
36

If defibrillation terminates the PVT and the patient returns to PVT, begin defibrillation at the last successful energy setting and increase as needed.
37
Ventricular Assist Devices | Information
Ventricular Assist Devices (VADs), also known as Heart Pumps, are surgically implanted circulatory support devices designed to assist the pumping action of the heart. Caring for these patients is complicated and every effort should be made to contact the patient’s primary caretaker (spouse, guardian etc.) and the VAD coordinator during your evaluation. Patients with a properly functioning VAD may NOT have a detectable pulse, measurable blood pressure or accurate oxygen saturation.
38
Ventricular Assist Devices | Adult
* Contact the VAD coordinator immediately; the phone number will be on the device and the equipment carrying bag. Take all equipment associated with the VAD system to the ED. * Locate patient’s emergency “bag” with backup equipment. * Treat Non–VAD associated conditions in accordance with the appropriate protocol. * Determine the type of device, assess alarms, auscultate for pump sounds. if needed, assist patient (caretaker) in replacing the device’s batteries or cables. * Locate the driveline site on the patient’s abdomen. BE CAREFUL not to cause any trauma to the site or driveline (wires). * If signs of hypo-perfusion, administer NORMAL SALINE: 1L * If there is bleeding at the site, apply direct pressure. AUSCULTATION FOR PUMP FUNCTION: Auscultate chest and upper abdominal quadrants – Continuous humming sound = pump is working.
39
Ventricular Assist Device | Unresponsive Patients
* EVALUATE UNRESPONSIVE PATIENTS CAREFULLY FOR REVERSIBLE CAUSES! * Perform a blood glucose level, if blood glucose is less than 60 mg/dl administer D10: 100mL. Refer to the hypoglycemia protocol. * Performing Chest Compressions risks rupturing of the ventricular wall leading to fatal hemorrhage. ONLY perform chest compressions when the patient’s VAD has no hand pump, the pump is not working and no other options exist to restart the VAD.
40
Ventricular Assist Device | Transport
Transport to the closest appropriate facility based on the patient’s chief complaint. There are two centers in Broward County. Cleveland Clinic 954-226-9196, Memorial Regional 954-232-5049 PACKAGING AN VAD PATIENT: Be aware of the cables, controller, and batteries. It may be best to place the stretcher straps under the LVAD cables so you are not creating any torque on the device. At a minimum, be aware of this extra hardware.
41
Patient presentations indicative of myocardial ischemia that do not meet “STEMI Alert Criteria”
should still be transported a STEMI facility.
42
CHF Pediatric
Call for orders
43
SPECIAL CONSIDERATIONS AFTER CARDIOVERSION | For patient’s who convert after two cardioversions OR after two or more shocks by their Implantable Cardioverter (ICD)
administer. AMIODARONE INFUSION: 150mg IV/IO (150mg into 50mL of Normal Saline) over 10 minutes (if Amiodarone has not already been administered).
