Tachycardia is a type of abnormal heartbeat, which is known as an arrhythmia. It occurs when your heartbeat is faster than normal, usually defined as being over 100 heartbeats per minute.

I was recently asked about the differences between one and three channel ambulatory ECG monitor recordings and whether, one was superior to the other. At CardioScan, we always use and recommend three channel 24-hour Holter monitors to be sure about our diagnosis of arrhythmias.

A normal blood pressure reading is considered 120/80 - if blood pressure reaches 130/90 or higher, then it is considered hypertension.

Arrhythmias are a group of conditions in which the heart beat is irregular and beats too fast or too slow.

Bradycardia is an abnormal heart rhythm, referred to as an arrhythmia. It is often defined as a heart rate that is too slow. For adults, a resting heartbeat of fewer than 50 beats per minute is classed as bradycardia.

Atrial fibrillation is an abnormal heart rhythm, which is known as a cardiac arrhythmia.

A cardiac arrhythmia is a rhythm disturbance of the heart which may require investigation using ambulatory electrocardiographic (ECG) monitoring.

What do you think? The annotation says “non-conducted supraventricular (atrial) ectopic”.

Recently, I reported two Holter monitor tracings that stated, “Mobitz I and II AV block”. Can both Mobitz I and II occur in the same patient? What do you think?
