What medicines can cause heart palpitations? ——Top 10 common drugs and countermeasures
Palpitations are a common uncomfortable symptom characterized by rapid heartbeat, irregular heartbeat, or discomfort in the precordial area. Many drugs may cause palpitations. The following are 10 drugs that may cause palpitations and related data that have been hotly discussed on the Internet in the past 10 days.
1. List of common drugs that cause palpitations
| drug class | specific drugs | Mechanisms that cause palpitations | risk level |
|---|---|---|---|
| doping | Caffeine, ephedrine | Stimulate the sympathetic nervous system | high |
| antidepressants | fluoxetine, venlafaxine | Affects the serotonin system | in |
| thyroid medication | Levothyroxine Sodium | speed up metabolism | high |
| Bronchodilators | Salbutamol, theophylline | Stimulate beta receptors | high |
| antihistamines | pseudoephedrine | Sympathomimetic effect | in |
| weight loss pills | Sibutramine | central stimulant effect | high |
| antibiotics | Azithromycin | Prolong QT interval | low |
| diuretics | Furosemide | electrolyte imbalance | in |
| antiarrhythmic drugs | Amiodarone | The effect of the drug itself | high |
| NSAIDs | Ibuprofen | Affect blood pressure | low |
2. Analysis of the mechanisms causing palpitations
1.Sympathetic nervous excitement: Caffeine, ephedrine and other drugs stimulate the sympathetic nervous system, causing the heart rate to increase.
2.electrolyte imbalance: Diuretics may cause hypokalemia, which may lead to cardiac arrhythmias.
3.QT interval prolongation: Certain antibiotics and antipsychotics may prolong cardiac repolarization time and increase the risk of arrhythmias.
4.direct cardiac effects: Antiarrhythmic drugs such as amiodarone may themselves cause arrhythmias.
3. High-risk groups
| Crowd category | risk factors | Things to note |
|---|---|---|
| heart disease patient | underlying heart disease | Avoid stimulant drugs |
| elderly | Decreased metabolic capacity | Reduce medication dose |
| Thyroid disease patients | Metabolic abnormalities | Monitor heart rate closely |
| People with electrolyte imbalance | Low potassium/low magnesium | Correct electrolytes before using medication |
| Drug users | Multiple drug interactions | Consult a doctor/pharmacist |
4. Countermeasures
1.Seek medical attention promptly: If you have persistent heart palpitations, you should seek medical attention promptly, especially if it is accompanied by chest pain and difficulty breathing.
2.Adjust medication: Your doctor may adjust your dose or change your medication.
3.Monitor heart rate: High-risk groups should regularly monitor heart rate and electrocardiogram.
4.avoid triggers: Reduce caffeine intake, avoid strenuous exercise, etc.
5.Supplement electrolytes: Appropriate supplement of electrolytes such as potassium and magnesium.
5. Latest research progress
According to medical journal reports in the past 10 days, researchers found:
1. The risk of heart palpitations caused by new antidepressants is 30% lower than traditional drugs.
2. Genetic testing can predict an individual’s susceptibility to drug-induced QT interval prolongation.
3. The heart rate monitoring function of smart bracelets has potential in the early detection of adverse drug reactions.
6. Expert advice
1. Read the instructions carefully before taking the medicine to understand the adverse reactions.
2. Inform your doctor of all medications you are taking, including supplements.
3. People with a history of heart disease should be closely observed during the initial period of medication.
4. Do not adjust the medication dosage yourself.
5. If symptoms of palpitations occur, record the onset time and duration promptly.
7. Summary
Many commonly used drugs may cause heart palpitations, and understanding these drugs and their mechanisms can help prevent and treat them promptly. The pros and cons should be weighed when taking medication, and high-risk groups should be more cautious. With the development of medicine, personalized medication and intelligent monitoring will better ensure medication safety.
