Pericarditis
Pericarditis is the inflammation of the pericardium around your heart. It can be caused by bacterial or fungal infection. Pericarditis causes the heart to rub the area surrounding it, which leads to more friction as it beats. It can be characterized by deep pain in the sternum, which can lead to adhesions over time.
Angina Pectoris
Angina pectoris is thoracic pain caused by a fleeting deficiency in blood delivery to the myocardium. This may be a result of stress-induced spasms of the coronary arteries or also from physical demands on the heart. This imbalance causes the myocardial cells to be weakened by the temporary lack of oxygen. If the imbalance goes on for a long period of time a myocardial infarction, or heart attack, can occur. The best way to avoid angina pectoris is to get regular exercise and eat a healthy diet.
Vavular Stenosis
Vavular stenosis is the narrowing of the heart valves. This imbalance can be caused by birth defects, endocarditis, or rheumatic fever.
Bradycardia & Tachycardia
Bradycardia and tachycardia are both homeostatic imbalances of the heartbeat. Bradycardia is when the heart rate is slower than normal, which can be 60 beats per minute or less. Having the imbalance of bradycardia is not necessary a risk to your health. Athletes frequently fall under the bradycardia diagnosis because their resting heart beat is much lower than the average person. Tachycardia is the opposite of bradycardia- the heart beat is abnormally fast beating around 160-240 beats per minute. Tachycardia is also known as 'V-tac'. Unlike bradycardia, it is not normal for the heart rate to rise this high.
