It details the typical procedure, including 12‑lead ECG acquisition on a treadmill or bicycle ergometer, concurrent blood pressure monitoring, and symptom assessment, with positivity defined by anginal pain and/or significant ST-segment shifts, and abnormal blood pressure responses. The content addresses diagnostic limitations, false-negative/false-positive risks, and contraindications such as acute coronary syndrome, decompensated heart failure, and severe hypertension. It further describes ambulatory ECG recording methods (continuous digital recording, patient-activated devices, and implantable loop recorders) for suspected arrhythmia and intermittent or infrequent but serious symptoms, plus Holter monitoring concepts. Echocardiography is introduced via transthoracic ultrasound imaging to rapidly assess cardiac structure and function, including estimates of left ventricular wall thickness and ejection fraction.",{"@graph":69,"@context":105},[70,84],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":35,"@type":76,"position":81},"https://docshare.wps.com/document/healthcare/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/investigations-in-cardiology/26829/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/investigations-in-cardiology/26829.png","ImageObject",300,407,{"name":92,"@type":93},"Theodore","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-09-20","2026-05-08",true,{"@type":102,"interactionType":103,"userInteractionCount":19},"InteractionCounter",{"@type":104},"ViewAction","https://schema.org",{"og:url":107,"og:type":108,"og:title":65,"og:site_name":95,"og:description":67},"https://docshare.wps.com/document/investigations-in-cardiology/26829","article",{"robots":110,"canonical":107},"index,follow",{"doc_id":112,"site_id":62},26829,1778200044,{"code":4,"msg":5,"data":115},{"doc_id":112,"user_id":116,"nickname":92,"user_avatar":117,"doc_module":4,"category_id":34,"category_name":35,"doc_title":65,"doc_description":67,"doc_content":66,"file_id":118,"file_url":119,"file_type":120,"file_size":121,"view_count":19,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":122,"language":123,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":66,"faqs":66,"seo_title":124,"seo_description":67,"update_tm":113,"read_time":125},7971461740886,"https://ap-avatar.wpscdn.com/davatar_3d24733baf745e90a7e4bdd5f77d97b2","cbCaic8bHsYzEt2T","https://ap.wps.com/l/cbCaic8bHsYzEt2T","pdf",779566,26,"English","Investigations in cardiology | PDF",66]
