Heartbeat control tu electrical system mak tak (Cardiac Conduction System) chungchang hi i zir mai ang u!

Engtin nge i thinlung chu chawlh hahdamna awm lovin, a hun takah, a rhythm khata a thawk tih i ngaihtuah ngai em? Kan mut lai te, kan hnathawh lai te, kan tlan lai te, he hun zawng zawng hian thinlung hian a hna a thawk tha famkim a ni. A chhan chu thinlung chhunga electrical system mak tak mai hi a ni. In chhunga wiring system ang bawkin hei hian thinlung chu a beng tur signal a pe a, chu chu electrical signal a ni. Vawiin hian he thinlung electrical conduction system chungchang hi kan sawi dawn a ni.

He thinlung electrical system hi eng nge ni?

A awlsam zawngin sawi ila, i thinlung electrical conduction system hi cell network bik a ni a, chu chuan heartbeat a control a ni. Nerve cell bakah muscle cell a pai bawk. He system hian electrical signal a thawn te hi thinlung a inzawm khawm a, chutah a hahdam tir thin a ni.

Kan in chhunga wiring system awm dan hi han ngaihtuah teh. Light on emaw fan on emaw turin wire kaltlangin current a luang ang bawkin, thinlung chhunga he electrical system hian heart muscle te hnenah signal a thawn bawk a, "contract hun a ni tawh," leh "thisen pump hun a ni tawh" tih te a hrilh bawk.

Hetiang kalphung hi control tu cell chi hnih a awm a, chungte chu:

• Conducting cells: Hengte hi thinlung chhung zawnga electrical signal phurtu ‘wire’ ang an ni.
• Muscle cells: Heng cell te hian electric signal an dawn chuan an inzawm khawm thin. Chu chu heng cell te avang hian thinlung a na tihna a ni. Wire chhunga current a kal chuan light bulb a eng ang bawkin.

Heng signal te hian thinlung chu taksa pum puia thisen pump turin thupek a pe a ni.

He system hmang hian eng nge thleng tak tak?

Heart electrical system hnathawh ber chu heartbeat tanna tur signal thawn hi a ni. Tin, thinlung hmun hrang hrang (upper leh lower chamber atria leh ventricles an tih) te chu engtikah nge an inzawm tur tih leh engtikah nge an relax tur tih a control bawk.

Hetianga inzawmkhawm leh damna kalphung hi chiang taka control a ni a, chuvang chuan thisen chu thinlungah a luang a, chuta tang chuan taksa pum puiah a luang lut a ni.

Heart attack a awm dan, step khat hnu step khat

Thinlung thawk apiangin he electrical signal hi thinlung chhunga kawng bik pakhatah a kal zel a ni. Track bik pakhata rel tlan ang maiin han ngaihtuah teh.

1. A bul tanna - Thinlung generator: Pakhatnaah chuan thinlung chhunga sinoatrial node (SA node) a awm .Electrical signal chu a koh part atang hian a intan thin. Hei hi thinlung "natural pacemaker" a ni. In pakhata main switch ang mai a ni.

2. Upper chamber contraction: He electrical signal hi thinlung chunglam chamber pahnih, atria -ah a darh a. Tichuan, chu pindan pahnih chu a inzawm khawm a, a chhunga thisen awm chu thinlung pindan hnuai lam thlengin a thawn ta a ni.

3. Traffic light: A dawtah chuan he signal hian atrioventricular node (AV node) an tih hmunah a thleng a. Hei hi traffic light ang mai a ni. Hetah hian signal chu second fraction khatin a delay a ni. A chhan chu a chung lam chamber pahnih chhunga thisen awm zawng zawng chu a hnuai lam chamber-a a chhuah theih nan hun pek a ni.

4. Main cord zawhin kal: Tichuan, signal tlai tak chu nerve fiber bik Bundle of His an tih hmangin a tla thla a.

5. Chamber hnuai lam inzawmkhawm: A tawp berah chuan he signal hi Purkinje fiber an tih wire tha tak tak network hmangin thinlung hnuai lam chamber pahnih, ventricles -ah a darh a ni. Chumi hnuah chuan heng hnuai lam chamber pahnih hi chak takin an inzawm khawm a, a sir khatah lungah thisen an pump a, a sir lehlamah taksa dang zawng zawngah thisen an pump lut bawk.

Heng step zawng zawng hi a inzawm khawm chuan heartbeat pakhat a zo vek a ni. Ngaihtuah teh, i thinlung electrical system chuan ni khatah heng signal sâng tam tak a thawn chhuak a, chu chuan i nung reng thei a ni.

Engtin nge he system hi control a nih?

I heart rate hi a inang reng reng lo a ni lawm ni? Bus hnunga i tlan laia i rate ang kha a ni lo a, mahse lehkhabu i chhiar laia i hmuh ang kha a ni. He rate hi i taksa peng pakhat i Autonomic Nervous System tih hian a control a ni . Hei hi SA node chu "work rang zawk" emaw "work slower" emaw tura hrilhtu a ni.

• Sympathetic nervous system: Hei hi ‘fight or flight’ response control tu a ni. He system hi hlauhna i neih hunah emaw, emergency-ah emaw, exercise i tih laiin emaw activate a ni a, i heart rate a ti chak hle.
• Parasympathetic nervous system: Hei hian ‘rest and digest’ response a control thin. I mut leh chawlh lai hian he system hi a thawk a, i heart rate a ti slow reng a ni.

He electrical system-a natna awm thei te chu engte nge ni?

A châng chuan, thinlung electrical system-ah hian tihsual engemaw zat a awm thei bawk. Tichuan, heart rhythm lama harsatna a lo awm ta a ni. Hengte hi heart rhythm disorder kan ti tlangpui.

Hetiang harsatna i neih leh neih loh hriat theihna tur symptoms

I thinlung electrical system-ah harsatna a awm chuan a hnuaia symptom thenkhat hi i nei thei ang:

• Thâwk harsa
• A rilru a na
• Palpitations (i rilru a na lutuk ang maia hriat) .
• Luak chhuak thei
• Thil hriatna hloh emaw, muhil emaw
• Thil danglam tak a chau tih hriatna

Doctor chuan i thinlung rhythm chu ECG (electrocardiogram) hmangin a enfiah thei a ni . Tin, ni engemaw zat emaw, kar engemaw zat emaw chhung chu i thinlung thawk dan enfiah turin hmanrua te tak te (heart monitor) vuah turin an ti thei bawk. Heng harsatnate hi enkawlna tur a awm a, chu chu damdawi leh pacemaker ang chi hmanrua dah te hi a ni .

Engtin nge thinlung electrical system hi a hrisel theih ang?

Heart rhythm lama harsatna thenkhat hi genetic factors vang a ni thei. Kan thlak danglam thei lo. Mahse, nunphung hrisel zawm hian i thinlung zawng zawng hrisel taka awm theihna kawngah kawng thui tak a zawh thei a ni.

• I taksa rihna hrisel tak vawng reng rawh: I san zawng nena inmil taksa rihna hrisel tak neih tum ang che.
• Meizial zuk loh tur: Meizial i zuk chuan bansan nghal rawh. Meizial zu (secondhand smoke) bula awm hi a pawi hle bawk.
• I damdawi ei dik: Damdawi dang, zunthlum leh thisen sang te tan i damdawi pek chu a hun takah ei thin ang che.
• Zu leh caffeine tihtlem: Zu leh caffeine awmna in tur coffee ang chi te tihtlem.
• Chaw tha tak tak ei rawh: Ei leh in tha tak tak ei rawh, chu chu thlai, thei, legumes leh whole grains te hi a ni.
• Exercise: Kar khatah minute 150 tal exercise chak tak nei rawh.
• Stress enkawl: Meditation, yoga, leh ṭhian rintlak tak nena inbiakna ang chi thil hmangin stress tihziaawm rawh.

Thinlung electrical system hi thil engemaw a kalsual hunah chauh kan hre tlangpui. Mahse he hmuh theih loh system hian thinlung hi min nung reng theihna tura a mamawh chakna leh rhythm petu a ni. Chuvangin, hei hi hriat chian a, a chunga chhinchhiahnate ngaihven a, nunphung hrisel tak neih hi i thinlung tan i tanpui theihna lian ber a ni.
