What is a dangerous heart rate? - Medical News Today
The count rates of cps and cpm are generally accepted and convenient practical rate measurements. They are not SI units, but are de facto radiological units of measure in widespread use. Counts per minute (abbreviated to cpm) is a measure of the detection rate of ionization events per minute. Counts are only … See more The measurement of ionizing radiation is sometimes expressed as being a rate of counts per unit time as registered by a radiation monitoring instrument, for which counts per minute (cpm) and counts per second (cps) are … See more Count rate does not universally equate to dose rate, and there is no simple universal conversion factor. Any conversions are instrument-specific. Counts is the … See more The surface emission rate (SER) is used as a measure of the rate of particles emitted from a radioactive source which is being used as a calibration standard. When the source is of plate or planar construction and the radiation of interest is emitting from one face, it is … See more Disintegrations per minute (dpm) and disintegrations per second (dps) are measures of the activity of the source of radioactivity. The SI … See more In radiation protection practice, an instrument which reads a rate of detected events is normally known as a ratemeter, which was first developed by R D Robley Evans in 1939. This mode of operation provides real-time dynamic indication of the radiation rate, … See more WebWhat’s meant by “frequent PVCs”? “Having a PVC or 2/min is relatively infrequent or occasional.

WebPatients with a high frequency of PVC (> 20-40% of all beats) may require more aggressive therapy independent of symptoms. There have been some reports of frequent PVCs resulting in a “tachycardia induced” cardiomyopathy, which can be reversed with successful elimination of PVCs by catheter ablation (ref 1).
