Heart Rhythm Disorders
Arrhythmias or heart rhythm disorders are conditions that causes changes in the normal heartbeat. There are numerous types of arrhythmias, for example, supraventricular tachycardia, sinus sick syndrome, atrial fibrillation, atrial flutter, and ventricular fibrillation. Signs and symptoms of an arrhythmia may include: Chest pain or discomfort Shortness of breath Palpitations Racing heart sensation Treatment for arrhythmias depend upon the cause. -
Atrial Fibrillation
Atrial fibrillation (AFib) describes a rapid, irregular heart rhythm. The irregular rhythm, or arrhythmia, results from abnormal electrical impulses in the heart. Atrial fibrillation may be treated with medications or surgery. There are many causes of atrial fibrillation, for example, pneumonia, heart disease, alcohol use, and thyroid problems. Symptoms of atrial fibrillation include chest pain and/or angina, nausea, dizziness, and heart palpitations. Atrial fibrillation is managed and treated with medication, medical procedures, and surgery. -
Congestive Heart Failure
Congestive heart failure (CHF) is a condition in which the heart can't pump enough blood and oxygen to the body's tissues. Learn about symptoms and treatment. -
Heart Attack
A heart attack is an interruption in blood flow to the heart muscle. Arterial plaque rupture is often the cause of a heart attack. Symptoms of a heart attack may include chest pain, shortness of breath, sweating, and nausea. Emergency heart catheterization and thrombolytic therapy may be used to treat a heart attack. -
Heart Attack Symptoms and Signs
The heart is a muscle like any other in the body. Arteries supply it with oxygen-rich blood so that it can contract and push blood to the rest of the body. When there isn't enough oxygen flow to a muscle, its function begins to suffer. Block the oxygen supply completely, and the muscle starts to die. -
Coronary Heart Disease
Coronary heart disease (CHD) is a group of different types of heart disease. Symptoms of heart disease depend on the cause and inclue chest pain or angina, shortness of breath, palpitations, and dizziness. Many conditions causes heart disease, for example, genetics, obesity, high cholesterol, and smoking. Treatment for heart disease depend on the cause and include diet and other lifestyle changes, medications, procedures, and surgery. The prognosis (outlook) and life span for someone with heart disease varies depending on the cause. -
How Much Heart Rate Variability Is Normal
Each person has their own distinctive heart rate variability (HRV), which cannot be measured against a chart, range, or averages. A person’s HRV can change from day to day and from season to season. A person’s age, gender, and even circadian rhythm can affect HRV. -
How Serious Is an Irregular Heart Beat
There are a number of causes for an irregular heartbeat. Sometimes, irregular heartbeat (arrythmia) is a relatively benign condition. In other contexts, irregular heartbeats may be the precursor to a heart attack or an indication of some other serious problem. -
What Are Target Heart Rates Chart
A target heart rate refers to what your heart rate should be while doing exercise, while a resting heart rate is the number of beats per minute (bpm) when at rest. An adult’s target heart rate is calculated based on their maximum heart rate, which is calculated based on a person’s age. -
What Is Dangerous and Normal Heart Rate
In general, a fast heart rate for adults is over 100 beats per minute (bpm). A normal resting heart rate is between 60 (beats per minute) and 100 (beats per minute) for people 15 years and older. -
Should I Be Worried About an Irregular Heartbeat
You should see a doctor right away if you have an irregular heartbeat (arrhythmia) and lightheadedness/fainting, chest pain, difficulty breathing, dizziness, swelling in your leg, symptoms persist or frequently return, coronary artery disease, congestive heart failure, family history of heart disease, high blood pressure, or diabetes. -
When Should I Be Worried About Heart Palpitations
Heart palpitations are not a cause for concern unless you also experience symptoms such as chest pain or pressure, difficulty breathing/shortness of breath, lightheadedness/fainting near-fainting spells, dizziness, excessive sweating, swelling in your leg, fatigue, weakness, confusion, anxiety, or symptoms persist or frequently return.
