Sample EasyECG Traces
It was discovered way back in the 17th century that the muscles of the body generate electricity and with manipulation of the signal the first ECG device was built. The peaks and troughs produced were named sequentially P - Q - R - S - T the next trough was called (the end of the T wave)(for some unexplained reason). With 21st century state of the art electronics NO manipulation is required SO -WYSIWIP- What You See Is What Is Produced! BioLecTrace produces a much clearer, well-defined and true trace and we are able to define the end of the T wave accurately. - In order to maintain some consistency we have followed ECG logic! So for clarity a BioLecTrace will have P - Q - R - S - T and U (being the end of the T wave). Because of the extreme sensitivity of BioLecTracer some traces in our database presented with more peaks and troughs than can be seen on a standard ECG device and may have P-Q-R-S-T-U-V-W-X-Y-Z.
A NORMAL EasyECG is identified and derived from a database compiled on thousands of traces taken over a period of 6 years on some 870 volunteers.
Of which the majority were very similar to the one displayed. Take note that the trace is consistent and regular. Now counting the heartbeats in the 10 seconds window above - there are 10 ¾ displayed. Multiplying this by 6 gives a heart rate of 67.5 (6 x 10secs = 1 Min) - On the standard ECG it is shown as - RR interval = 67bpm or Vent Rate = 67bpm
TheEasyECG Trace displayed is Tachycardia.
Now counting the heartbeats in the 10 seconds window above there are 18.5 displayed. Multiplying this by 6 gives a heart rate of 111 (6 x 10secs = 1 Min) - RR=111bpm. Tachycardia is the clinical description of a heart rate that is over 100 beats per minute.
The EasyECG Trace displayed is Bradycardia.
Now counting the heartbeats in the 10 seconds window above there are 6.7 displayed. Multiplying this by 6 gives a heart rate of 40.2 (6 x 10secs = 1 Min) - RR=45bpm. Bradycardia is the clinical description of a heart rate that is under 50 beats per minute.
The EasyECG Trace displayed is Arrhythmia.
The displayed trace is irregular, erratic, not consistent or is NOT a consistent rhythm! There are many forms of irregularities each displaying a different looking picture. The (catchall) clinical description for a trace that is like this is Arrhythmia. If your trace looks like this you should seek medical advice especially if you also have symptoms. Arrhythmia is the clinical description of heartbeats that individually vary in time intervals producing many varying patterns over a period of time. There are many different arrhythmias
This person has LongQT Syndrome
- The heart condition LongQT Syndrome is so called because it is characterised by an extended QT interval on an ECG trace, it can cause blackouts or sudden death. - A prolonged QT interval can be acquired through some medication or is a genetic inherited condition. - The ECG Text Book explanation of LongQT is WHEN the time interval from the beginning of the QRS complex to the end of the T wave on a standard ECG is abnormally long after correction for the heart rate - THEN it’s LongQT. - However it is over complicated and accepted to be flawed in a number of ways. The end of the T wave is NOT universally identified. It is accepted that two different cardiologists (and ECG devices) can give a different QT interval on the same ECG trace. There is conjecture as to the end of the T wave! - Additionally there are a number of different mathematical equations to correct for the heart rate. -
With -BLT LongQT is when the time interval from the Q wave to the U wave is higher than 59% of each, and most all beats - THEN it’s LongQT.
Short R is the BioLecOlogy description of a trace that presents with an R wave that is extremely short. It is usual to see a larger T wave when a short R has been presented. - This person has no signs or symptoms of any ill health. But because this trace is quite distinctly different from the normal and there are others who have presented with similar looking traces it is now identified as being SR.
Short T is the BioLecOlogy description of a trace that presents with a T wave that is extremely short. It is usual to see a larger R wave when a short T has been presented. - This person has no signs or symptoms of any ill health. But because this trace is quite distinctly different from the normal and there are others who have presented with similar looking traces it is now identified as being ST.
