Hyperkalemia
This ECG displays many of the features of hyperkalaemia:
• Disappearance of p waves
• ST elevations (best seen in aVR and chest leads)
• Broad, bizarre QRS complexes that merge with subsequent ST segment and T wave.
• Sine waves (best seen in V3)

Mitral stenosis
The ECG shows “Sinus tachycardia” and “S1Q3T3 pattern”, two most common ECG findings in PTE. These findings are neither sensitive nor specific for PTE, Thus ECG findings only in combination with physical symptoms suggest PTE.
Here are the most common ECG findings in patients with PTE:
• Sinus tachycardia
• S1Q3T3 pattern
• New-onset atrial fibrillation or flutter
• incomplete right bundle branch block
• right axis deviation
• T-wave inversion in leads V1 to V4
