Answer:
Rocky mountain spotted fever is a diseases which occur seasonally in the month april and september. This diseases begin 3 to 14 days after an infected bite from tick, as they are spotted in tall grass and shrubs.

This diseases require a proper treatment with in a week otherwise, a person can die in two weeks once the symptoms developed.
Yes, the signal processing occurs inside the ECG machine. The ECG machine captures and processes the electrical signals generated by the heart, creating an ECG tracing that can be analyzed to assess the heart's function. Despite their limitations, ECGs are a valuable diagnostic tool in cardiology.
True, the signal processing does occur inside the ECG machine. An electrocardiogram (ECG) is a recording of the electrical impulses of the cardiac muscle that are detected by electrodes placed on the skin. The heart generates a complex electrical signal that initiates the heart rhythm, causing the atria and ventricles to contract and relax in the correct sequence. This electrical signal is processed within the ECG machine to create an ECG tracing, which can then be analyzed to assess the heart's function.
ECGs are a crucial diagnostic tool in cardiology, as they can reveal detailed information about both normal and abnormal heart function. An ECG tracing comprises several components, each of which corresponds to important electrical events within the heart, and so can provide a comprehensive insight into cardiac muscle activity. The number of leads used in an ECG determines how much information the electrocardiogram can provide, with a 12-lead ECG offering the most detailed view.
However, despite their diagnostic power, ECGs do have their limitations. For example, certain heart conditions may not be detectable on an ECG, and it does not provide information about the effectiveness of the heart's pumping action. Nevertheless, the ECG machine itself plays a critical role in capturing and processing the heart's electrical signal to provide these essential diagnostic insights.
