Tachycardia is a heart rhythm disorder characterized by the heart rate rising above 100 beats per minute at rest. The heart working faster than normal can affect the circulatory system and, in some cases, may be a sign of serious cardiovascular problems.<\/p>\n
Tachycardia symptoms usually appear as a feeling of palpitations, dizziness, shortness of breath, chest discomfort, and weakness. The increase in heart rate may make it difficult for the body to meet its oxygen needs, and in advanced cases, fainting or confusion may occur.<\/p>\n
Causes of tachycardia include stress, intense exercise, fever, anemia, excess thyroid hormone, and certain medications. In addition, cardiological conditions such as heart valve diseases, coronary artery disease, and heart muscle disorders can also cause the heart rhythm to accelerate.<\/p>\n
Tachycardia treatment is planned according to the underlying cause and may include lifestyle modifications, medication therapy, or interventional methods. After cardiological evaluation, treatment options such as rhythm-regulating medications, catheter ablation, or in some cases a pacemaker may be applied.<\/p>\n
| What You Need to Know<\/td>\n | Information<\/td>\n<\/tr>\n |
| Definition<\/td>\n | Tachycardia is the condition in which the heart beats more than 100 times per minute at rest. It has subtypes such as sinus tachycardia (physiological or pathological), supraventricular tachycardia, and ventricular tachycardia.<\/td>\n<\/tr>\n |
| Normal Heart Rate<\/td>\n | In adults, the normal resting heart rate is generally between 60-100 beats per minute.<\/td>\n<\/tr>\n |
| Types of Tachycardia<\/td>\n | – Sinus Tachycardia: Occurs in situations such as exercise, stress, and fever. – Supraventricular Tachycardia (SVT): A fast rhythm disorder originating from the atrium. – Ventricular Tachycardia (VT): A serious rhythm disorder originating from the ventricle and may be life-threatening. – Atrial Fibrillation and Atrial Flutter: Fast heartbeats due to abnormal atrial activity.<\/td>\n<\/tr>\n |
| Common Symptoms<\/td>\n | – Feeling of palpitations – Dizziness – Fainting or feeling as if one may faint – Shortness of breath – Chest pain – Weakness<\/td>\n<\/tr>\n |
| Emergency Symptoms<\/td>\n | – Loss of consciousness – Severe chest pain – Difficulty breathing – Drop in blood pressure<\/td>\n<\/tr>\n |
| Possible Causes<\/td>\n | – Physical or emotional stress – Anemia – Fever – Hyperthyroidism – Heart diseases (coronary artery disease, heart failure) – Electrolyte imbalances – Alcohol, caffeine, nicotine – Certain medications or medication side effects – Drug use (e.g. cocaine, amphetamines)<\/td>\n<\/tr>\n |
| Risk Factors<\/td>\n | – Age – Family history of heart disease – High blood pressure – Diabetes – Obesity – Sedentary lifestyle<\/td>\n<\/tr>\n |
| Diagnostic Methods<\/td>\n | – Physical examination and medical history taking – ECG (Electrocardiogram) – Holter monitor (24-72-hour ECG recording) – Exercise stress test – Echocardiography – Blood tests (thyroid, electrolyte, anemia, etc.)<\/td>\n<\/tr>\n |
| Treatment Options<\/td>\n | – Lifestyle changes: Reducing caffeine\/alcohol, stress management, regular exercise – Medication therapy: Beta blockers, calcium channel blockers, antiarrhythmic medications – Electrocardioversion: Restoring heart rhythm to normal with an electric shock – Catheter ablation: Destroying the abnormal electrical focus – Implantable cardioverter defibrillator (ICD): Used in life-threatening rhythm disorders<\/td>\n<\/tr>\n |
| Follow-up and Control<\/td>\n | – Regular cardiology follow-up – ECG checks – Evaluation of medication effectiveness and side effects – Monitoring the underlying cause<\/td>\n<\/tr>\n |
| Prevention Methods<\/td>\n | – Healthy and balanced nutrition – Regular exercise – Avoiding smoking and alcohol use – Stress management – Keeping existing diseases (hypertension, diabetes, etc.) under control<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n |
