Detailed explanation-1: -The atypical symptoms tend to occur more commonly among those who are older, female, diabetic (possibly due to autonomic neuropathy), hypertensive, and with prior heart failure. They were reported in 5.7% and 12.3% of patients with unstable angina and NSTEMI, respectively [2].
Detailed explanation-2: -An anginal equivalent is a symptom such as shortness of breath (dyspnea), diaphoresis (sweating), extreme fatigue, or pain at a site other than the chest, occurring in a patient at high cardiac risk. Anginal equivalents are considered to be symptoms of myocardial ischemia.
Detailed explanation-3: -A patient with right ventricular failure would most likely present with: an enlarged liver. A prolonged PR interval: indicates an abnormal delay at the AV node.
Detailed explanation-4: -Give the shock as quickly as possible. Immediately after shock delivery, resume CPR (beginning with chest compressions) without delay and continue for 5 cycles (or about 2 minutes if an advanced airway is in place), and then check the rhythm (Box 5).
