Final answer:
An ECG provides a detailed look at heart function, identifying damaged heart tissue, monitoring subtle changes over time, and incorporating portable technology for use in various settings.
Step-by-step explanation:
Besides the event pages showing heart rate trends in 20-minute intervals, an Electrocardiogram (ECG) can provide extensive information about the heart's condition. An ECG can help identify regions of damaged heart tissue, known as infarcts, by reflecting electrical waves that are visible in lead potentials. Also, subtle changes indicating slight or gradual damage can be noticed through comparisons of recent and older ECGs. Another key aspect is that due to the variances in an individual's heart shape, size, and orientation, these are factors that can cause variations in ECGs. Modern ECG technology has advanced and portable ECG monitors can now be included in wearable devices and utilized in remote settings, providing real-time cardiac monitoring. Moreover, ECGs are capable of detecting systole, the period of heart muscle contractions, and the T wave, which represents the ventricles' repolarization during a cardiac cycle.
