Angina pectoris is typically caused by physical or emotional stress. Symptoms usually last no more than 10 minutes and are relieved by rest.
The normal heart rate for a newborn is 140 – 160 and an infant’s is 120 – 140 beats per minutes. Children between the ages of 1-6 have a heart rate of 100 – 120, while children over the age of 6 have a heart rate of 80 – 100 BPM.
The three-flap valve is called the tricuspid valve, and it divides the right atrium from the right ventricle.
Your first action would be to administer oxygen and place the patient in a comfortable position; next, if not contraindicated, you would request permission to administer nitroglycerin. You should first obtain a set of vital signs to ensure he is not in cardiogenic shock. Never put defibrillator pads onto a conscious patient with a pulse; this procedure is contraindicated. AED pads are not serving the same function as the electrodes used by ALS providers to monitor the heart rhythm.
Ventricular tachycardia often converts to ventricular fibrillation, a life-threatening heart rhythm that the AED is designed to correct.

The mitral valve is located between the left atrium and ventricle and prevents blood from flowing back into the left atrium.
Myocardial pain is often difficult to determine because it can take on many different characters; however, patients most commonly (over 40% of the time) describe the pain of a myocardial infarction as a crushing, squeezing pressure that radiates outward to the arms and upper back.
There is no information to indicate that the patient requires ventilatory support. Any patient experiencing chest discomfort should receive the highest possible concentration of oxygen.
Oxygen-rich blood reaches the left atrium from the lungs via the pulmonary veins; then, the left ventricle pumps it out to the rest of the body.
This woman shows classic signs of cardiac compromise: dull chest pain, sudden onset of sweating, and difficulty breathing.
While there is limited information that people in extended periods of cardiac arrest may benefit from CPR before defibrillation, overwhelming information indicates that defibrillating very early in a “fresh” arrest situation will provide the best opportunity for correcting the most common cause of cardiac arrest—ventricular fibrillation.
Geriatric patients do not always present the clear-cut signs and symptoms of cardiac problems. With the limited information given, this patient could be suffering from any of the above cardiac conditions, plus a wide variety of pulmonary illnesses as well.
Blood enters the heart through the Inferior/superior vena cavae, to the right atrium, then the right ventricle. It then goes to the lungs through the pulmonary vein, returning through the left atrium, then the left ventricle, leaving through the aorta.
