2022 ACS Defibrillator

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. If this is ACS with Aslanger's pattern , the ST depression vector of subendocardial ischemia (due to simultaneous 3 vessel or left main ACS) is directed toward lead II (inferior and lateral). CPR was initiated immediately.

Assessing the Severity The severity of an electrical burn depends on several factors: the type of current (AC or DC), voltage, the pathway of the current through the body, the duration of contact, and the victim’s overall health. As EMTs, we’re always prepared to address these life-threatening complications alongside the burns.

The fire department, who operate at an EMT level in this municipality, arrived before us and administered 324 mg of baby aspirin to the patient due to concern for ACS. She was defibrillated and resuscitated. Most studies examine undifferentiated ACS cohorts, with only a handful providing separate data. References: 1.

Recall that, in the setting of ACS symptoms, ST depression that are maximal in leads V1-V4 (as opposed to V5 and V6) not attributable to an abnormal QRS complex is specific for OMI. When the ICD was finally interrogated, the syncopal events and shocks correlated with two VF events that were defibrillated successfully.

Several 200 J shocks did not terminate the VF, so a second defibrillator was applied for double sequential defibrillation with 400 J. She was defibrillated perhaps 25 times. After completing the ACS algorithm with amiodarone and lidocaine, there are diminishing returns on further treatments. SanzRuiz, R., Solis, J., &

In ACS, chest pain is the warning sign of ongoing ischemia. In this case, you should get a second defibrillator and perform double sequential external defibrillation (DSED). Simply attach a second defibrillator as shown in the diagram below and deliver max shocks from both devices simultaneously. in absolute terms!

After ruling out for ACS, the patient underwent angiography where he was found to have severe stable disease, which was already known. This would be approximately 95% of the patient's maximum predicted sinus rate. This demands an explanation -- sepsis, hemorrhage, withdrawal, etc. Calling sinus tachycardia raises more questions than answers.
