micrometer
from wikipedia "A micrometre is one-millionth of a metre (1/1000 of a millimetre, or 0.001mm). Its unit symbol in the International System of Units (SI) is μm"
No, an electrocardiogram (ECG) is a painless test that involves placing electrodes on your skin to measure the electrical activity of your heart. It is a non-invasive and safe procedure.

The RR interval of ECG vary during normal respiration because of the sinus arrhythmia.
Adrenaline increases heart rate and conduction velocity in the heart, which can lead to changes in the ECG. These changes may include a shortening of the PR interval, widening of the QRS complex, and an increase in heart rate.
In ECG, the term "vector" refers to the direction and magnitude of the electrical activity in the heart. It represents the sum of all electrical forces during a particular phase of the cardiac cycle. Vectors are used to analyze different aspects of heart function and can help identify abnormalities in the heart's electrical activity.
The amplitude of an ECG wave is typically measured in millimeters (mm) on the vertical axis of the ECG graph. It represents the voltage or electrical activity of the heart muscle during each phase of the cardiac cycle.
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
probably abnormal ECG?
The typical amplitude of a P wave on an electrocardiogram (ECG) is usually less than 0.25 mV (2.5 mm).
ECG An electrocardiogram (ECG) is a test that records the electrical activity of the heart. ECG is used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker). See also stress test and Holter monitor (24h). = Intensive-care unit = An intensive care unit (ICU), critical care unit (CCU), intensive therapy unit or intensive treatment unit (ITU) is a specialized department used in many countries' hospitals that provides intensive care medicine. Many hospitals also have designated intensive care areas for certain specialities of medicine, as dictated by the needs and available resources of each hospital. The naming is not rigidly standardized.
Common methods used to perform an ECG test include placing electrodes on the chest, arms, and legs to measure the heart's electrical activity. A non-wave ECG differs from traditional ECG readings by focusing on the overall shape and pattern of the heart's electrical signals rather than just the individual waves.
The electrical activity of the heart.
An ECG is an electrocardiography. It is used to detect and record the electrical impulses of the heart. An ECG is non-invasive and may be used as a diagnostic tool to detect abnormalities.
ECG and EKG are the same used to map the electrical activity of heart
No, an electrocardiogram (ECG) is a painless test that involves placing electrodes on your skin to measure the electrical activity of your heart. It is a non-invasive and safe procedure.
In an ECG, the standardization mark typically refers to a calibration signal that represents a specific amplitude. This is usually set at 10 mm (or 1 mV) in height for each small square on the ECG paper, which helps ensure accurate interpretation of the heart's electrical activity. When the ECG is properly standardized, it allows for consistent comparison of different ECGs over time or among different patients.
The ECG sign of subendocardial ischemia is ST segment depression. Note that ECG is used more now that EKG.
