A one step procedure known to consistently stop Severe Angina Pectoris or Myocardial infarction (MI), commonly known as a heart attack. Apply for these key words: heart attack, cardiovascular episode, cardiac arrest, irregular heartbeat, chest pain, angina, cardiac, heart, heart problem. 
Angina pectoris occurs when the flow of blood to the myocardium (heart muscle) is insufficient to meet the metabolic demands of the myocardium. Fibrin, cholesterol, and other substances can form a plaque in the coronary arteries restricting the flow of oxygen and nutrients to the myocardium. Sometimes, a plaque can rupture and form a clot that blocks coronary blood flow. The impaired blood flow can cause angina or even myocardial infarction (heart attack). 
Common angina symptoms include pressure, tightness, pain, squeezing or aching sensation in the chest or arms that may spread to the neck, jaw or back, sometimes with associated nausea, indigestion, heartburn or abdominal pain, shortness of breath, cold sweat, fatigue, lightheadedness, or sudden dizziness.  

It is beyond the scope of this paper to describe all the treatments for angina pectoris or myocardial infarction.

When blood flow decreases or stops to a part of the heart, causing damage to the heart muscle.

The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Often occurs in the center or left side of the chest and lasts for more than a few minutes and may feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat, or feeling tired or exhausted. About 30% of people have atypical symptoms. Women more often have atypical symptoms than men. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock, or cardiac arrest.

The King Method (TKM®) focuses on the electrical system (or bio-electromagnetic system) of the body to stop the malfunction temporarily to apply appropriate procedures to prevent further occurrences. TKM provides more in-depth study to address the causes, but not in this app.
