  1. This is a good explanation for people who like math, and it helped me finally sum up everything I learned over the past two days.

  2. Please do some videos on doppler echocardiography, TOE and TTE pleasee

  3. It feels like I'm in trig all over again. Ha.

  4. Osmosis is really a great learning platform. – eBio Education

  5. Hallo I am from Indonesia I want to riview this video:

    EKG secara khusus menunjukkan bagaimana gelombang depolarisasi setiap detakan jantung yang merupakan gelombang mutan positif. Dan tampilanya bergantung pada rangkaian elektroda yang digunakan. Sel elektroda ini disebut lead 2 misalnya dengan satu elektroda di tengah kanan dan dikaki kiri, pada dasarnya saat gelombang bergerak ke arah elektroda kaki kiri akan mendapatkan defleksi positif, seperti defleksi positif besar ini sesuai dengan gelombang yang bergerak ke bawah vertikal kiri dan kanan. Pada saat seseorang beristirahat sel akan bermuatan relatif negatif dibandingkan diluar lingkungan dan ketika mereka mendepolarisasi, sel-sel menjadi bermuatan positif, meninggalkan muatan sedikit negatif diluar lingkungan. Elektroda akan mendeteksi muatan yang ada diluar sel jika muatan yang berada diluar sel cenderung bermuatan positif maka EKG akan menunjukkan tracking tersebut sebagai defleksi positif-semakin besar dipol semakin besar defleksi sehingga akan menunjukkan gambar mengarah ke atas. Sebliknya jika muatan diluar sel cenderung negatif maka akan terjadi depolarisasi dan gambar akan menunjukkan garis lurus.

    Thank You

  6. Limb leads: I, II, III (bipolar); aVR, aVL, aVF (unipolar)
    Chest leads: V1-V6 (precordial)

  7. What group does aVR fall under?
