A stethoscope can be used to listen to the heart, the auscultations and valve sounds.
There are many ways to "measure" a heart beat. The most effective tool is the ECG (electrocardiogram) which measures electrical activity of the heart. Because the electrical activity (electrical signals originating from the sino-atrial and atrio-ventricular nodes of the heart) is a direct indicator of the physical activity of the heart (contraction, relaxation, valve activity, etc) you can determine almost everything you need to know about the heart using an ECG, including its physical orientation within the mediastinum (sac containing the heart within the chest cavity).
The time between each electrical impulse can be measured, thus giving elapsed time between each beat, and allowing you to determine how many times the heart contracts (beats) every minute - known as heart rate (HR). Presumably, this is what you mean by "measuring heartbeats", but an ECG is capable, as explained, of doing much more.
Hope this helps, if you would like me to expand or go into more complex detail, let me know.

How to improve accuracy in a measuring instrument?
To improve accuracy in a measuring instrument, you can calibrate it regularly using a known standard. Ensure the instrument is properly maintained and cleaned to prevent any errors. Use proper measurement techniques and follow manufacturer's guidelines for usage.

What instrument is used for measuring liquids?
A graduated cylinder or a measuring cup is typically used for measuring liquids. These instruments have marked increments to help accurately measure volumes of liquid.
What is a Precision and non precision measuring instrument?
A precision measuring instrument provides accurate and consistent measurements, typically to a high degree of precision (e.g. micrometers or calipers). Non-precision measuring instruments provide general measurements but with less accuracy and consistency, such as tape measures or rulers.
Why is the use of zero-error necessary in a measuring instrument?
Zero-error is necessary in a measuring instrument because it ensures accuracy in measurements by accounting for any inherent discrepancies in the instrument itself. By calibrating the instrument to have a zero-error, any readings taken will be more reliable and consistent, allowing for more precise measurements to be made.
