Medical - Medical: Cardiology
English term or phrase: sinus node
Definition from Medical University of South Carolina:
bundle of excitatory tissue found in the right atrium that functions as the pacemaker of the heart

Example sentence(s):
  • The autonomic nervous system, the same part of the nervous system as controls the blood pressure, controls the firing of the sinus node to trigger the start of the cardiac cycle. medterms.com
  • If the sinus node is not functioning normally -- due to damage from surgery, drugs, congenital heart defects or other causes -- the heartbeat may become very slow with a decrease in blood pressure. University of California
  • Extrinsic sinus mechanisms of sinus node dysfunction could be drug effects or due to autonomic influences. The important drugs which could suppress sinus node function are beta blockers, non-dihydropyridine calcium channel blockers (e.g. verapamil and diltiazem), digoxin, clonidine, methyl dopa, class IA, IC and III antiarrhythmic agents and lithium.

קשרית הגת


Definition from own experience or research:
קוצב הלב הטבעי. מורכבת מאשכול של תאי שריר מיוחדים בעלייה הימנית של הלב, המייצרים אותות חשמליים שגורמים להתכווצויות הלב בקצב סדיר.

Example sentence(s):
  • קשרית-הגת ממוקמת בחלק העליון של הפרוזדור הימני. קשרית זו שולחת גירויים חשמליים המתפשטים במהירות בשריר הלב וגורמים לו להתכווץ. - BeOK  
  • מרווח ה-PR מייצג את משך הזמן שלוקח לזרם חשמלי לעבור מהעליה דרך קשרית הגת ועד לדה פולריזציה החדרית, כלומר - ההתכווצות של החדרים. - ynet
