Heart Ecg Interpretation. If it is at 90 degrees then the complex is isoelectric i e. When looking at a 12 lead ecg a few logistics must be understood. One of the most useful and commonly used diagnostic tools is electrocardiography ekg which measures the heart s electrical activity as waveforms. When electrical activity or depolarisation travels towards a lead the deflection is net positive.
One of the most useful and commonly used diagnostic tools is electrocardiography ekg which measures the heart s electrical activity as waveforms. Determine heart rate on the ecg to determine whether bradycardia a normal heart rate or tachycardia is present requires the knowledge to calculate the heart rate on the ecg. An ekg uses electrodes attached to the skin to detect electric current moving through the heart. The standard ecg is in 12 leads includes three limb leads i ii and iii three augmented limb leads avr avl and avf and six chest leads v 1 v 2 v 3 v 4 v 5 and v 6. Divide 300 by this number to calculate heart rate. If it is at 90 degrees then the complex is isoelectric i e.

These signals are transmitted to produce a record of cardiac activity. These signals are transmitted to produce a record of cardiac activity. The r and s wave are the same size. An ekg uses electrodes attached to the skin to detect electric current moving through the heart. The ekg is a printed capture of a brief moment in time. When the activity travels away from the lead the deflection is net negative.
