一个烙印朋友得了心脏病，装了什么东西，可以检测到，不过认识的得过心脏病的朋友，几个都去世了

Types of Heart Attack Detection Devices: 

• External ECG Monitors: 

  These devices, like the KardiaMobile and Holter monitors, record the heart's electrical activity using electrodes attached to the body. They can detect irregular heart rhythms and other changes that may indicate a heart attack or other cardiac issues. 

   

• Implantable Monitors: 

  Devices like the Guardian Heart Attack Warning System are implanted under the skin and continuously monitor internal heart signals. They can detect subtle changes in electrical activity and oxygen levels, potentially providing a warning up to 20 minutes before a full heart attack. 

   

• Wearable Sensors: 

  The Infrasensor wristband is a novel device that can detect specific biomarkers, like cardiac troponin, in the bloodstream, indicating heart muscle damage. 

   

• CardioMEMS: 

  This device is used to monitor advanced heart failure and can detect subtle changes in pulmonary artery pressure.
