ECG series 2

Middle aged female presenting with chest pain, nausea and diaphoresis.

“There are six ECGs taken over a 44 minute period of a middle aged female pt with no PHx, that presented with CP, diaphoresis and nausea/vomiting. Pt went into VF and reverted with 1x DCCS prior to 12-lead being performed. Initial 3 lead taken showed hyperacute T waves in Lead I, with STD in Leads II and III.

ECGs 1, 3 and 4 were taken with the pt experiencing CP, diaphoresis, nausea and vomiting with ECGs 2, 5 and 6 being taken when the pt had <1/10 pain and resolution of her diaphoresis and nausea.

The pt was taken to Cath Lab ~10/60 after having the last ECG taken. Whilst moving onto the table, her symptoms returned with associated elevation of her ST segments. 5/60 later, the pt had a VF arrest which didn’t respond to DCCS attempts. Pt was placed on the LUCAS device and her proximal LAD was stented with ROSC after ~40/60. Pt had a full neurological recovery. ”

37-year old man with atypical chest pain.

  • Normally healthy 37-year old male.
  • Presented with pressure-like retrosternal chest pain, gradually worsening severity over 1 hour period.
  • Atypical in character — i.e. non-pleuritic, exacerbated with leaning forward, relieved by laying supine. No diaphoresis, nausea, vomiting. No radiation.
  • Had used sildenafil in the preceding 24 hours. No other drugs / medications / precipitants.
  • Physical exam unremarkable. BP 130/90, P 86. Sats 96% RA.
  • No changes on serial ECGs (this is the second ECG in the series, taken at ~5h post onset of pain).
  • This case was a difficult call as no cardiology cover / PCI available overnight — confirmed STEMI would have required thrombolysis.
  • Possibilities considered by the treating doctors included extensive STEMI, pericarditis and coronary artery spasm.

VS 2

94-year old patient with palpitations.

  • Presented with 1/52 Hx of intermittent palpitations, nausea, weakness and presyncope
  • Discharged from hospital 1/52 prior following an admission for palpitations/rapid AF;   discharged with an increased verapamil dose.
  • Background Hx of PPM for AF (?tachy brady), hypothyroidism, and HTN.
  • Meds = warfarin, sotalol, verapamil, thyroxine, ISMN, digoxin.
  • Asymptomatic at time of ECG recording.
