Beta-blockers tau siv dav hauv kev tswj hwm ntawm angina, qee yam tachyarrhythmias thiab lub plawv tsis ua haujlwm, nrog rau kev kub siab. (tsis zoo chronotropic nyhuv) thiab blockade ntawm beta1-receptors nyob rau hauv lub myocardium txo lub plawv contractility (tsis zoo inotropic nyhuv).
Puas yog beta-blockers inotropic lossis chronotropic?
Vim tias feem ntau muaj qee theem ntawm kev sib haum xeeb ntawm lub siab, beta-blockers tuaj yeem txo cov kev mob siab rau uas ib txwm stimulate chronotropy (lub plawv dhia), inotropy (contractility), dromotropy (hluav taws xob conduction) thiab lusitropy (so).
Puas yog beta-blockers tsis zoo lossis zoo chronotropic?
Beta-blockers tau siv los kho cov kab mob plawv ischemic, vim negative chronotropic thiab inotropic zog, yog li ua rau txo qis hauv myocardial noj cov pa thiab cov as-ham, ua kom zoo dua. sib npaug ntawm cov khoom noj khoom haus thiab cov khoom noj uas muab los ntawm cov ntshav coronary.
Puas beta-blockers puas muaj cov teebmeem chronotropic?
Beta blockers cuam tshuam rau ntshav siab los ntawm ntau lub tswv yim, suav nrog tsis zoo chronotropic nyhuvuas txo qis lub plawv dhia thaum so thiab tom qab kev tawm dag zog, qhov tsis zoo inotropic cuam tshuam uas txo qis lub plawv, txo qis. sympathetic outflow los ntawm lub hauv paus paj hlwb (CNS), thiab tsub kom renin tso tawm.
YDo beta-blockers muaj qhov tsis zooCov nyhuv inotropic?
Nws yuav tsum tau hais tias txawm tias tsawg npaum li cas ntawm beta- blockers ua rau tsis zoo inotropic teebmeem thiab tuaj yeem ua rau muaj qhov tsis zoo ntawm hemodynamics thiab cov tsos mob plawv tsis ua haujlwm hauv cov neeg mob plawv.

Puas yog angiotensin receptor blockers tib yam li beta blockers?
Losartan yog tsis yog beta-blocker, txawm li cas los xij, zoo li beta blockers, losartan (hu ua ARB lossis angiotensin receptor blocker) kuj yog siv los kho cov ntshav siab. ARBs txo cov ntshav siab los ntawm kev thaiv qhov kev txiav txim ntawm cov tshuaj hormones uas ua rau koj cov hlab ntsha kom nruj, thaum beta blockers txo koj lub plawv dhia nyuaj npaum li cas.
Puas yog nws tsis pom zoo lossis tsis pom zoo?

Puas yog epinephrine muaj txiaj ntsig zoo chronotropic?
Thaum noj tsawg, epinephrine ua haujlwm feem ntau yog qhov zoo inotropethiab chrontrope. Txawm li cas los xij, cov koob tshuaj ntawm epinephrine feem ntau yog muab tshuaj kho mob txaus los txhawb ob qho tib si α thiab β receptors. Qhov txiaj ntsig zoo chronotropic yog dab tsi?
Puas yog pov thawj uas tsis pom zoo lossis tsis pom zoo nrog kev sib cav?
Cov lus foob: Ib qho kev thov uas tsis pom zoo lossis tsis pom zoo nrog qhov thesis / thov. (Qhov no yuav yog tus neeg tawm tsam qhov kev xav.) Rebuttal: Cov pov thawj uas tsis pom zoo lossis tsis pom zoo rau qhov kev foob foob. (Nov yog qhov uas tus menyuam kawm ntawv teb rau tus yeeb ncuab thiab qhia tias vim li cas lawv qhov kev sib cav tsis muaj zog.
Puas yog qhov tsis zoo yog qhov zoo?
tus zoo tsis zoo li lwm yam ntawm nws homlossis ntawm kev nyob ib leeg hauv hom lossis yam ntxwv: Vim nws lub cev thiab tus cwj pwm tsis zoo, osprey yog cais hauv nws tsev neeg. Qhov zoo tshwj xeeb txhais li cas? 1 yog tib yam ntawm ib hom tshwj xeeb;
