What can be seen on ECG with AVRT

A

200-300bpm, ST depression and positive aVR

111
Q

What is the main issue with AVRT

A

Doesn’t allow ventricles to fully fill and gives reduced CO (cardiac output)

112
Q

What is AVNRT

A

Av node Reentry tachy - Reentry pathway in the AV node

113
Q

Management for SVT?

A

Vagal manoeuvres (carotid massage, valsalva)
Adenosine
Verpamil
DCC

114
Q

How does adenosine work??

A

Slows electrical conductivity

115
Q

How does verapamil work?

A

Calcium channel blocker (blocks calcium and thus contractility of the heart and causes blood vessel dilatation)

116
Q

What is broad complex tachy defined as?

A

QRS>120 ms

117
Q

What is VT

A

Ventricular tachycardia
Has 2 subgroups sustained and non-sustained

118
Q

What is non-sustained VT

A

> 3 consecutive episodes that resolve that are <30sec

What is a main symtpom of chronic heart failure

A

Pulmonary oedema
( backlog of blood in ventricles/atria/pulmonary veins and lugs = more pressure and fluid in the space = pressure of blood filtration into interstitial space = oedema)

148
Q

What is ejection fraction

A

percentage of blood that leaves left ventricle in each contraction

149
Q

What is normal ejection fraction

A

> 50%

150
Q

What is persevered ejection fracture heart failrue

A

Diastole has issues (ventricle isn’t opening up/refilling properly leading issue to space.= more pressure etc)

151
Q

What are the main causes?

A
  • ischaemia
  • valvular disease
  • HTN
  • arrhythmia
  • cardiomyopathy
152
Q

What investigations would you do for heart failure

A

BNP
ECH
Echo (ejection fraction)
Bloods CXR/Lung function

153
Q

what is the New York heart association classification (NYHAC)

A

SEVERITY OF SYMPTOMS

154
Q

What is class 1 NYHAC

A

NO LIMITATION

155
Q

What is class 2 NYHAC

A

Comfortable at rest but symptoms with ordinary activities

156
Q

What is class 3 NYHAC

A

Comfortable at rest but symptomatic with any activity

157
Q

what is class 4 NYHAC

A

Symptomatic at rest

158
Q

Tx for chronic heart failure

A

ABAL

159
Q

what does ABAL mean

A

Ace inhibitor (ramipril) (ARB can be used if not tolerated or valve disease)
Beta blocker (Bisoprolol)
Aldosterone antagonist (spironolactone)
Loop diuretic (furosemide/bumetanide)

160
Q

4 types of valvular disease?

A

Aortic stenosis
Aortic regurg
Mitral stenosis
Mitral regurg

161
Q

What is the most common valvular disease

A

Aortic stenosis

162
Q

What does aortic stenosis stop the heart doing

A

Narrows valve = reduced blood flow from left ventricle to aorta to body

163
Q

What sound does aortic stenosis make

A

Crescendo decrescendo

164
Q

Where does an aortic stenosis murmur radiate

A

Carotids in the neck

165
Q

OSCE tip to emphasise murmur of aortic stenosis

A

Sit forward
Deep breath
Exhale
Hold

166
Q

Usual cause of aortic stenosis

A

Calcification (age related)
Bicuspid aortic valve
Rheumatic disease

167
Q

What is aortic regurg

A

Incompetent aortic valve
Always back flow from aorta (after contraction) back into left ventricle

168
Q

What sound does aortic regurg make

A

Early diastolic (soft) murmur
Decrescendo

169
Q

What is the S1 sound depicting

A

Closure of atrioventricular valve
- tricuspid
- bicuspid

170
Q

What is S2 sound depicting

A

Closure of the semilunar valves
- pulmonary
- aortic

171
Q

What is systole

A

Contraction

172
Q

Austin flint?

A

Murmur heard at apex beat in aortic regurg, rumbling

173
Q

Collapsing pulse is seen in?

A

Aortic rgeurg

174
Q

Causes of aortic regurg

A

Age related weakness
Bicuspid
Connective tissue discords (marfans/ehlers danlos)

175
Q

What is mitral stenosis

A

Narrowing of the bicuspid valve restricting blood flow from left atrium to left ventricle

176
Q

What sound does mitral stenosis give?

A

Mid-diastolic, low pitched rumbling (low blood flow velocity)

177
Q

Other signs of mitral stenosis?

A

Malar flush

178
Q

Causes of mitral stenosis

A

Rheumatic
Infective endocarditis

179
Q

What is mitral regurg

A

Incompetent mitral valve allow back flow from left ventricle to left atrium

180
Q

What complications come from mitral valve regurg

A

Back flow of blood = CHF
Reduced ejection fracture

181
Q

What sounds does the mitral regurg murmur sound like

A

Pansystolic murmur

182
Q

Where does mitral valve regurg radiate

A

Left axilla,

183
Q

Causes of mitral regurg

A

Age
Ischameia
Rheumatic
Connective tissues

184
Q

OSCE tips to hear mitral regurg murmur

A

Lying on left

185
Q

Investigations for valvular disease

A

Echo
