Glasgow ECG Interpretation Algorithm

ECG Interpretation Algorithms

Ever since a ECG machine was developed, there have been a number of modifications and advancements that has helped technology evolve. In 1970s,  initial attempts at developing  the first ECG interpretation algorithm were put in. Since the accuracy of those algorithms were not up to the mark, several databases were built by various institutions to 9compare ECGs and check for accuracy. The methods for interpretation might include not limited to:

  1. Time-frequency methods
  2. Neural networks
  3. Comparison with templates

ECG – Electrocardiographs

Did you know that ECG as a concept originated in 1901? They coined a term Electrocardiograph as Electro meant Electrical Activity, Kardio meant Heart and Graph meant to write. Briefly put, a ECG measures the electrical activity of the heart and traces it as a graph helping the physician understand how your heart works. From then (machines with analog electronics), to now(with analog-to-digital converters), Electrocardiographs have evolved and come a long way.

WHO and Blood pressure guidelines

At this day and age, blood pressure is a household term and the awareness around maintaining a ‘normal’ blood pressure is increasing. If you’re wondering how and why, check out our article on blood pressure that would help you understand it deeper.

While 120/80 is a well known common number that is associated with blood pressure, above what range is it called ‘Hypertension’ and when is it called ‘Hypotension’?

In common practice, we consider anything below and equal to Systolic Blood Pressure 120 and Diastolic Blood Pressure 80 as normal whereas anything above 140 and 90 are considered higher. Continue reading “WHO and Blood pressure guidelines”
