    {
        this.InitializeComponent();
        mytimer.Interval = new TimeSpan(0, 0, 0, 1, 0);

Try this: 

private readonly DispatcherTimer _mytimer = new DispatcherTimer();
public MainPage()
{
    InitializeComponent();
    _mytimer.Interval = new TimeSpan(0, 0, 0, 5, 0);
    _mytimer.Tick += Mytimer_Tick;
    _mytimer.Start();
}

private void Mytimer_Tick(object sender, object e)
{
    Debug.WriteLine($"executado: {DateTime.Now}");
}

Note: You must use the _mytimer.Start(); method to start Timer

In my tests I made some changes and it worked.

Replace: 

mytimer.Tick += new EventHandler(mytimer_Tick);

by: 

mytimer.Tick += mytimer_Tick;

And replace the mytimer_Tick method signature. 

private void mytimer_Tick(object sender, EventArgs e)

by: 

private void mytimer_Tick(object sender, object e)
