sinus horn
right sinus horn→openings of superior vena cava and inferior vena cava
left sinus horn→coronary sinus and oblique vein of left atrium(左心房斜静脈)

4 structure which is fused after the lateral folding
dorsal aortae→aortic sac
heart tubes→primitive heart tube
vitelline veins→sinus venosus

cardiac glycosides
mechanism,adverse effects
digoxin
direct inhibition of Na+/K+ATPase
indirect inhibition of Na+/Ca2+ exchanger
→↑[Ca2+]i→positive inotropy
stimulates vagus nerve→↓HR
☆hyperkalemia, yellow vision, AV block,GI disturbances

the third heart sound(S3)
the fourth heart sound(S4)
S3 early diastole(can be normal in children,trained athlete,pregnancy)
→sign of volume overload
S4 late diastole→consider abnormal including pressure overload,severe hypertension
cardiology

dressler syndrome
manifestation,treatment
(occurs several weeks after MI)
chest pain,pericardial friction rub
NSAIDs,corticosteroid(because this is caused by autoimmune phenomenon)
cardiology
HirotoShishido
congenital long QT syndrome
Romano-Ward syndrome→autosomal dominant,no deafness
Jarvell and Lange-Nielsen syndrome→autosomal recessive, sensorineural deafness

the first visible change of myocardial infarction in light microscope
when neutrophic infiltration can be seen

antiarrhythmics
(sodium channel blocker+potassium channel blocking effects as well)

SVT treatment
(supraventricular tachycardia)
β blocker, Ca blocker(blocks AV node),adenosine
+vagal maneuver,cardioversion,ablation
Ca blocker is contraindicated with pseudoVT(WPW+AF),retrograde AVRT
(when AV node is blocked, retrograde AVRT will be aggravated)
cardiology

more common papillary muscle rupture
posteromedial papillary muscle rupture
(because it has a single blood supply from PDA(posterior descending artery))
→MR
cardiology

artery of Adamkiewicz
blood supply
(=great ventral radicular artery,大前根動脈)supplies ASA(anterior spinai artery) below T8
can be affected by aortic aneurysm repair, aortic dissection
