Tsis tas li ntawd, cov tshuaj tiv thaiv arrhythmic ua rau arrhythmia li cas? Arrhythmias yog ua los ntawm kev cuam tshuam hauv koj lub plawv hluav taws xob. Antiarrhythmics qeeb cov hluav taws xob hauv koj lub siab kom nws tuaj yeem rov ua haujlwm tas li.
Tsis tas li ntawd, 4 chav kawm ntawm cov tshuaj tiv thaiv arrhythmic yog dab tsi?
Cov tshuaj tiv thaiv kab mob antiarrhythmic:
- Qib I - Sodium -channel blockers.
- Chav Kawm II - Beta-blockers.
- Qib III - Potassium -channel blockers.
- Chav Kawm IV - Calcium-channel blockers.
- Lwm yam - adenosine. - electrolyte ntxiv (magnesium thiab potassium ntsev) - digitalis compounds (cardiac glycosides)
Dab tsi yog qhov kev kho mob zoo tshaj rau arrhythmia?
