What are the drugs that can lower heart rate but not blood pressure

The drugs that can lower heart rate but not blood pressure mainly include non dihydropyridines in beta blockers and calcium channel blockers. These drugs lower heart rate by regulating heart function, but have a small impact on blood pressure and are suitable for patients who need to control heart rate but have normal blood pressure. Common medications include metoprolol, bisoprolol, and diltiazem.

1. Beta blockers: These drugs lower heart rate by blocking cardiac beta receptors, slowing down heart rate, and weakening myocardial contractility. Metoprolol is a commonly used beta blocker, suitable for patients with hypertension, angina pectoris, and arrhythmia. Bisoprolol has a higher selectivity for β 1 receptors and a more significant impact on heart rate, making it suitable for patients with chronic heart failure and arrhythmia. When using this type of medication, attention should be paid to possible side effects such as fatigue, dizziness, and cold hands and feet.

2. Non dihydropyridine calcium channel blockers: These drugs block calcium channels in the heart, reducing the entry of calcium ions into myocardial cells, thereby slowing down heart rate and weakening myocardial contractility. Diltiazem is a common non dihydropyridine calcium channel blocker, suitable for patients with angina pectoris and arrhythmia. Verapamil also belongs to this category and is suitable for patients with hypertension and arrhythmia. When using this type of medication, attention should be paid to possible side effects such as constipation, headache, and low blood pressure.

3. Other auxiliary measures: In addition to medication treatment, lifestyle adjustments can also help control heart rate. It is recommended that patients maintain regular exercise, such as 30 minutes of aerobic exercise every day, such as brisk walking, swimming, or cycling. Diet should reduce the intake of high salt and high-fat foods, and increase fiber rich foods such as whole grains, vegetables, and fruits. Maintaining a good psychological state, avoiding excessive tension and anxiety, also helps stabilize heart rate.

The drugs that lower heart rate but not blood pressure mainly include beta blockers and non dihydropyridine calcium channel blockers, such as metoprolol, bisoprolol, and diltiazem. These drugs lower heart rate by regulating heart function, but have a relatively small impact on blood pressure. Patients should be aware of possible side effects when using these medications and adjust their lifestyle accordingly, such as regular exercise and a healthy diet, to achieve better heart rate control. If the heart rate continues to be abnormal, it is recommended to seek medical attention promptly and receive diagnosis and treatment from professional doctors.
