Key result

Electrocardiographic abnormalities occur in approximately 50% of patients with subarachnoid haemorrhage, which can resemble myocardial damage and lead to misdiagnosis if not appreciated.

Why the study?

What are the electrocardiographic changes associated with subarachnoid haemorrhage and how do they influence management?

Implication

Recognition of ECG changes in subarachnoid haemorrhage may avert cardiac misdiagnosis; Level 4 evidence leaves open effects on outcomes.

Key Points

  • This review aims to evaluate electrocardiographic changes in patients with subarachnoid haemorrhage and their clinical implications.
  • Reviewed existing literature on electrocardiographic changes in subarachnoid haemorrhage.
  • Analyzed post-mortem studies to assess myocardial damage in affected patients.
  • Discussed potential explanations for observed electrocardiographic abnormalities.
  • Approximately 50% of patients show electrocardiographic abnormalities post-subarachnoid haemorrhage.
  • Most post-mortem studies reveal no evidence of myocardial injury despite ECG changes.
  • Misinterpretation of these changes can delay surgical interventions or lead to inappropriate treatments.

Electrocardiographic abnormalities

Awareness of ECG abnormalities in subarachnoid hemorrhage is crucial to prevent misdiagnosis of primary cardiac disease and avoid delays in appropriate surgical treatment.

Cite This Study

Anthony Harries (1981) conducted a review in Subarachnoid haemorrhage. Subarachnoid haemorrhage was evaluated. Electrocardiographic abnormalities occur in approximately 50% of patients with subarachnoid haemorrhage, which can resemble myocardial damage and lead to misdiagnosis if not appreciated.
