Cardiology Flashcards
what type of murmur is aortic regurgitation
early diastolic
what type of murmur is aortic stenosis
ejection systolic
what type of murmur is mitral regurgitation
pan systolic
what type of murmur is mitral stenosis
mid diastolic
most common cause of mitral stenosis
rheumatic fever
acute management of Atrial Fibrillation
immediate DC cardioversion
management of paroxysmal Atrial Fibrillation
dont require long term anti-arrythmic therapy
flecainide (pill in pocket)
electrical cardioversion
done in A fib.
patient needs to be anti coagulated (DOaC e.g. edoxaban)
or transesophageal echo to check for thrombus
pharmacological cardioversion
flecainide or amiodarone
still needs anticoagulation
treatments for persistent/permanent a fib
verapamil
carvedilol
digoxin
aortic dissection presentation and classification
tearing chest pain
Stanford type A = ascending aorta
type B = descending aortia
investigation + management of aortic dissection
CT aortogram/angiogram = diagnosis
ECG / echo to investigate
Type A = surgical (valve graft)
Type B = medical (labetalol to control arterial BP)
indications of amiodarone
arrhythmias, only used as last resort
what is brugada syndrome, affected population, Mx
inherited arrhythmia
causes sudden death in east asian males with structurally normal hearts
Implantable Cardioverter - Defibrillator
ECG for brugada syndrome
cove shaped ST segment with negative T wave
how to diagnose brugada syndrome
ECG (cove shaped ST segment with negative T wave)
+ family history / V fib / syncope
pathophysiology of Wolff-Parkinson White syndrome
accessory pathway opens between SA node and AV node, ventricles contract too early (accessory pathway doesn’t account for the normal delay)
supraventricular tachycardia
ECG findings for WPW
delta wave (slurred upstroke of the QRS)
Mx for stable and unstable patients with WPW
stable: vagal manoeuvres/meds (amiodarone)
unstable: immediate DC cardio version
definitive treatment for WPW
radiofrequency ablation of the accessory pathway
Wellen syndrome ECG
biphasic/negative T wave in leads V2 + V3
cause of wellen syndrome
stenosis of LAD, major risk for MI
meds for heart failure
ABAL
ACEi , beta blocker, aldosterone antagonist, loop diuretic
meds for heart failure
ABAL
ACEi , beta blocker, aldosterone antagonist, loop diuretic
irregular R R interval
a fib
what is cardiac resynchronisation therapy (CRT) used for
connects to the ventricles, allows them to contract properly. used in severe heart failure
what is cardioversion used for
reset to sinus rhythm
what is a permanent pacemaker used for
takes over entire electrical conduction
broad complex is defined as?
> 120ms
presentation of aortic stenosis
pulmonary edema
low volume pulse
low pulse pressure
slow rising carotid pulse
ejection systolic murmur and 4th heart sound
forceful apex beat
unheard A2 (aortic closure sound)
indications for embolectomy vs thrombolysis
embolectomy: remove an embolus (a blood clot originating from elsewhere and moving to this location)
thrombolysis: break down a clot that has formed there
non specific symptoms e.g. cough, fatigue, weight loss, hoarseness, night sweats
dockyard worker
malignant pleural mesotheliomaM
Mx of a Malignant pleural mesothelioma
combination therapy (chemo + radio)
management of peripheral arterial disease
- 12 week exercise program
- Stenting and angioplasty
- Bypass surgery
- Naftidrofuryl oxalate
Mx of acute arterial embolus
fogarty embolectomy
initial Mx of hyponatremia
fluid restriction
