EKG, Echo, Cath

Question 1

Describe the findings

Answer 1

• NSR ( +1 )
• ST and/or T wave abnormalities suggesting electrolyte disturbances ( +1 )
• Prolonged QT ( +2 )
• Hypocalcemia ( +4 )
  
  • ​prolonged QT = long ST segment + normal duration T wave
  • characteristic of LQT-3 subtype
  • Ical = 2.7 in this patient

Question 2

Describe the findings

Answer 2

• NSR ( +1 )
• Dual-chamber pacemaker (DDD), normal functioning ( +2 )
• Bi-V pacing / cardiac resynchronization ( +4 )
  
  • ​RA lead is appropriately sensing the underlying SR and therefore triggering the RV lead to fire
  • dual V-pacing spkes occurring just after each other (best seen in V2)
  • upright (RBBB morphology) QRS complex in V1 –> suggests Bi-V

Question 3

Describe the findings

Answer 3

• NSR ( +1 )
• AV block, 1st degree ( +1 )
  
  • subtle P-waves with prolonged PR in V2-V4 –> NSR with 1st degree AV block
• IVCD, nonspecific ( +1 )
• ST and/or T wave abnormalities suggesting electrolyte disturbances ( +2 )
• Hyperkalemia ( +4 )
  
  • ​K = 9.2; marked QRS widening

Answer 4

• SB ( +1 )
• Borderline normal EKG or normal variant ( +1 )
• Normal variant, early repolarization ( +4 )

Question 5

Describe the findings:

Answer 5

RCA dissection

• mid-RCA:
  
  • small, linear cleft indicative of a vessel dissection
• IVUS confirmed dissection

Question 6

Describe the findings:

Answer 6

• MR ( +4 )
• LV aneurysm ( +2 )
• MV, systolic anterior motion ( +1 )

*****Dx: HCM with prior apical MI –> LV apical aneurysm

******mid-cavity obliteration during systole –> LVOTO

*******mechanism of MR in this setting –> systolic anterior motion of anterior MV

Question 7

Describe the findings

Answer 7

• RV
• Pulmonary valve stenosis ( +4 )
  
  • ​post-stenotic dilation of the pulmonary artery on RV gram will confirm the diagnosis

Question 8

Describe the findings

Answer 8

• Severe MS ( +6 )
• Rheumatic mitral valve disease ( +2 )
• LAE ( +1 )

Question 9

Describe the findings

Answer 9

• Aortic dissection, Type A ( +6 )
• Aortic enlargement or aneurysm ( +2 )
• Mild-moderate AR ( +1 )
• Mild-moderate MR ( +1 )

Question 10

Describe the findings

Answer 10

• Atrial myxoma ( +6 )
• Mild-moderate MS ( +2 )

Question 11

Describe the findings

Answer 11

• RCA fistula ( +4 )
  
  • ​SA node coming off proximal RCA –> large atrial myxoma
• Severe RCA stenosis ( > 75%) ( +4 )

Question 12

Describe the findings:

Answer 12

• Coarctation of Aorta ( +4 )
  
  • ​known history of coarctation
  • underwent surgery at age of 10
  • follow up revealed 25 mmHg residual pressure gradient across the coarctation
• Aortic aneurysm ( +4 )

Question 13

Describe the findings

Answer 13

• NSR ( +1 )
• LAE ( +1 )
• RAD ( +1 )
• IVCD, nonspecific type ( +2 )
  
  • criteria for LBBB are not met due to lack of slurred R-waves in the lateral limb leads
• PPM malfunction - failure to capture ( +4 )
• PPM malfunction - failure to sense ( +4 )
  
  • ​atrial pacing exists, but there is a failure of the atrial spikes to capture (spikes without any evidence of conduction)
  • atrial spike seen just after the second QRS complex of the tracing that is clearly occuring too son after the previous P-wave ( < 240 ms) –> atrial lead is failing to appropriately sense the intrinsic P-wave

Question 14

Describe the findings

Answer 14

• VT ( +4 )

Question 15

Describe the findings

Answer 15

• Membranous VSD ( +6 )
  
  • ​perimembranous VSD near the LVOT
  • patient with history of Down Syndrome (Trisomy 21)
  • presented with a murmur and was found to have a small, hemodynamically insignificant VSD

Question 16

Describe the findings:

Answer 16

• Anomalous LCx ( +4 )
  
  • ​benign anomaly, LCx will always course posterior to the aorta and never between the great vessels

Answer 17

• NSR ( +1 )
• LAD ( +1 )
• LVH ( +4 )
